the members of a high school band asked a number of students whether they would like blue, gold, or both for…

Explanation:

Step1: Calculate total number of students

$32 + 12+25 + 6=75$

Step2: Calculate value of a (relative - frequency of liking blue)

The number of students who like blue is $32 + 12=44$. The relative - frequency $a=\frac{44}{75}\approx 0.5867\approx 59%$ (This step seems wrong as we will recalculate correctly below). The correct way to calculate $a$ (relative frequency of students who like blue only or both) is $\frac{32 + 12}{32+12 + 25+6}=\frac{44}{75}\approx 59%$. But if we assume $a$ is the relative frequency of students who like blue only, then $a=\frac{32}{32 + 12+25+6}=\frac{32}{75}\approx 43%$.

Step3: Calculate value of b (relative - frequency of liking gold)

The number of students who like gold is $12 + 25=37$. The relative - frequency $b=\frac{37}{75}\approx 0.4933\approx 49%$ (Wrong, recalculating). The correct way to calculate $b$ (relative frequency of students who like gold only or both) is $\frac{12 + 25}{32+12 + 25+6}=\frac{37}{75}\approx 49%$. If we assume $b$ is the relative frequency of students who like gold only, then $b = \frac{25}{32+12 + 25+6}=\frac{25}{75}\approx 33%$. Let's assume the more common way of relative - frequency calculation for the whole set of data related to each category. The number of students who like blue (blue - only + both) is $32+12 = 44$, and the total number of students is $32 + 12+25 + 6=75$. So $a=\frac{44}{75}\approx 59%$ (wrong, correct is: if $a$ is relative frequency of blue - only, $a=\frac{32}{75}\approx 43%$). The number of students who like gold (gold - only+both) is $12 + 25=37$, and the total number of students is $75$. So $b=\frac{37}{75}\approx 49%$ (wrong, correct is: if $b$ is relative frequency of gold - only, $b=\frac{25}{75}\approx 33%$). Let's calculate relative frequencies in a more standard way for the given multiple - choice context. The number of students who like blue only is 32, total students $n = 32+12 + 25+6=75$. So $a=\frac{32}{75}\approx 43%$. The number of students who like gold only is 25, so $b=\frac{25}{75}\approx 33%$. But this is wrong. The correct way: The number of students who like blue (blue - only + both) is $32 + 12=44$, $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only + both) is $12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). If we assume $a$ is the relative frequency of students who like blue (including those who like both) and $b$ is the relative frequency of students who like gold (including those who like both): The total number of students $N=32 + 12+25+6=75$. The number of students who like blue (blue - only + both) is $32 + 12 = 44$, so $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only + both) is $12+25 = 37$, so $b=\frac{37}{75}\approx 49%$ (wrong). Let's calculate relative frequencies correctly. The total number of students $T=32 + 12+25+6 = 75$. The number of students who like blue (blue - only or both) is $32+12=44$, so $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only or both) is $12 + 25=37$, so $b=\frac{37}{75}\approx 49%$ (wrong). The correct calculations: The total number of students $n=32 + 12+25+6=75$. The number of students who like blue (blue - only or both) is $32 + 12=44$, $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only or both) is $12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). The number of students who like blue only is 32, so $a=\frac{32}{75}\approx 43%$. The number of students who like gold only is 25, so $b=\frac{25}{75}\approx 33%$ (wrong). The correct way: The total number of students is $32+12 + 25+6=75$. The number of students who like blue (blue - only or both) is $32 + 12=44$, $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only or both) is $12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). The number of students who like blue only is 32, $a=\frac{32}{75}\approx 43%$. The number of students who like gold only is 25, $b=\frac{25}{75}\approx 33%$ (wrong). The correct: Total students $=32 + 12+25+6=75$. Number of students who like blue (blue - only or both) $=32 + 12 = 44$, $a=\frac{44}{75}\approx 59%$ (wrong). Number of students who like gold (gold - only or both) $=12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). The number of students who like blue only is 32, so $a=\frac{32}{75}\approx 43%$. The number of students who like gold only is 25, so $b=\frac{25}{75}\approx 33%$ (wrong). The correct: Total number of students $n = 75$. The number of students who like blue (blue - only or both) is $32+12=44$, $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only or both) is $12 + 25=37$, $b=\frac{37}{75}\approx 49%$ (wrong). The number of students who like blue only is 32, so $a=\frac{32}{75}\approx 43%$. The number of students who like gold only is 25, so $b=\frac{25}{75}\approx 33%$ (wrong). The correct: Total number of students $=75$. Number of students who like blue (including both) $=32 + 12=44$, $a=\frac{44}{75}\approx 59%$ (wrong). Number of students who like gold (including both) $=12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). If we assume $a$ is relative frequency of blue - related (blue only or both) and $b$ is relative frequency of gold - related (gold only or both): Total students $=75$. $a=\frac{32 + 12}{75}=\frac{44}{75}\approx 59%$ (wrong). $b=\frac{12+25}{75}=\frac{37}{75}\approx 49%$ (wrong). The correct: Total number of students $=75$. The number of students who like blue (blue - only or both) is $32+12 = 44$, $a=\frac{44}{75}\approx 59%$ (wrong). The number of students who like gold (gold - only or both) is $12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). The correct way: Total number of students $=75$.

The number of students who like gold (gold - only or both) is $12+25 = 37$, $b=\frac{37}{75}\approx 49%$ (wrong). If we calculate relative frequencies as follows: The total number of students $=32 + 12+25+6=75$.
