Explanation / Answer
Solution:- The probability of selecting a girl, given that the flip resulted in heads is 0.5714
Since flip resulted in head, so we have to select the student from 12 boys and 16 girls
The probability of selecting a girl, given that the flip resulted in heads = 16/28
The probability of selecting a girl, given that the flip resulted in heads = 16/28 = 0.5714
