Assuming all 16 babies selected for the study are boys of 6 to 8 month of age, this problem will be solved easily with a Bernoulli distribution:

Probability of success: p = 0.25

Total number of trials: n = 16

Number of success: x = 5

P = C(n,x) p^{x }(1-p)^{(n-x)}

P = 16!/(5!*11!) * (0.25)^{5} * (0.75)^{11 }= 0.18
