you pick a card at random. what is p(odd)? write your answer as a percentage.

Explanation:

Step1: Count total outcomes

There are 4 cards, so total number of outcomes $n = 4$.

Step2: Count favorable outcomes

The odd - numbered cards are 5 and 7, so number of favorable outcomes $m=2$.

Step3: Calculate probability

The probability formula is $P=\frac{m}{n}$. So $P=\frac{2}{4}=\frac{1}{2}$.

Step4: Convert to percentage

To convert a fraction to a percentage, multiply by 100. So $\frac{1}{2}\times100 = 50%$.

Answer:

50%
