Question

in a group of students, 65 are in band, 83 are in choir, and 72 are in art club. what is the probability that a randomly selected student isnt in choir?

\\(p(\text{not in choir}) = \quad\\%\\)

round your answer to the nearest whole percent.

Explanation:

Calculate total number of students

$$ \text{Total} = 65 + 83 + 72 = 220 $$

Calculate number of students not in choir

$$ \text{Not in choir} = 220 - 83 = 137 $$

Calculate probability as a percentage

$$ P(\text{not in choir}) = \frac{137}{220} \approx 0.6227 \approx 62\% $$

Answer:

In a group of students, 65 are in band, 83 are in choir, and 72 are in art club. What is the probability that a randomly selected student isn't in choir?
