Question

Giving a test to a group of students, the grades and gender are summarized below

A B C Total
Male. 9 4 10 23
Female 7 20 12 39
Total. 16 24 22 62

If one student is chosen at random,
Find the probability that the student did NOT get an "C"

Answer 1

The total number of students who did not get a "C" is 16 + 24 = 40.

The total number of students is 62.

Therefore, the probability that the student chosen at random did not get a "C" is:

P(not C) = 40/62

P(not C) = 0.645 or approximately 64.5%

Therefore, there is a 64.5% chance that the student chosen at random did not get a "C".
