Question

A test was given to a group of students. The grades and gender are summarized below:
A B C Total
Male 14 9 18 41
Female 7 13 12 32
Total 21 22 30 73
(a) If one student is chosen at random from those who took the test, Find the probability that the student got a 'A' GIVEN they are female.

Answer 1

Answer:

The probability that the student got a 'A' and is female is 9,59%

Step-by-step explanation:

To get the probability  equally likely of choosing a specific student, we use the following formula

P=# of possibilities that meet the condition / #of equally likely possibilities.

# of possibilities that meet the condition= 7

#of equally likely possibilities= 73

P(fem grade A)= 7/73= 0,0959=9,59%
