a spinner is divided into 4 sections. the spinner is spun 100 times. the probability distribution shows the results. what is $p(1leq xleq3)$? enter your answer, as a decimal, in the box.

Answer

Explanation:

Step1: Identify probabilities from the chart.

The bar chart shows the probabilities for each section: $P(x=1) = 0.32$ $P(x=2) = 0.24$ $P(x=3) = 0.28$

Step2: Sum the probabilities for $x=1, 2, 3$.

The probability $P(1 \le x \le 3)$ is the sum of the probabilities for $x=1$, $x=2$, and $x=3$. $$ P(1 \le x \le 3) = P(x=1) + P(x=2) + P(x=3) $$ $$ P(1 \le x \le 3) = 0.32 + 0.24 + 0.28 $$

Step3: Calculate the final probability.

$$ P(1 \le x \le 3) = 0.84 $$

Answer:

0.84
