Question

Approximately 50% of babies born are boys. Five coins are tossed 60 times and the coins showed two tails out of the five coins 40 times. Determine the experimental probability of a woman having 2 boys out of 5 children.

P(2 boys out of 5) = 5⁄6 = 83.3%

P(2 boys out of 5) = 2⁄3 = 66.7%

P(2 boys out of 5) = 2⁄5 = 40%

P(2 boys out of 5) = 1⁄30 = 3.3%

P(2 boys out of 5) = 1⁄20 = 5%

Answer 1

40% is the probability of a women having 2/5 baby's born as a boy.
