In a class of 22 students, 9 are female and 7 have an A in the class. There are 8 students who are male and do not have an A in the class. What is the probability that a student chosen randomly from the class does not have an A?
There are a total of 22 students in the class.
Out of these, 7 have an A and 8 are male and do not have an A. This means that there are 22 - 7 - 8 = 7 students who are female and do not have an A.
So, the probability of choosing a student who does not have an A is:
(Number of students without A) / (Total number of students)
= (7 + 8) / 22
= 15 / 22
= 0.68
Therefore, the probability that a student chosen randomly from the class does not have an A is 0.68 or 68%.
