ABCTotalMale1881137Female341219Total21122356If one student is chosen at random from those who took the test, find the probability that the student was female GIVEN they got a 'C'. Round to at least 3 decimal places.____.

Answer 1

1. 0.286

2. 0.522

Step-by-step explanation:

First question:

Taking into account the table, 14 students got a C, and 4 of them were female. So, the probability that the student was female given that they got a 'C' is equal to

P = 4/14 = 0.286

Second question:

In this table, 23 students got a 'C', and from the 23, 12 were females. So, the probability that the student was female given that they got a 'C' is equal to

I P = 12/23 = 0.522
