Question

In a school where 36% of students buy lunch, what is the probability that a randomly chosen student will not buy lunch?

a) Can't be determined
b) 64%
c) 36%
d) 50%

Answer 1

The probability that a randomly chosen student will not buy lunch is 64%, calculated by subtracting the 36% who do buy lunch from 100%.

Step-by-step explanation:

If 36% of students buy lunch at a school, the probability that a randomly chosen student will not buy lunch is the complement of the 36%. Since probabilities always add up to 100%, you simply subtract 36% from 100% to find the probability of the opposite event occurring:

100% - 36% = 64%.

Therefore, the probability that a randomly chosen student will not buy lunch is 64%, which corresponds to option b) 64%.
