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) px (1-p)(n-x)
P = 16!/(5!*11!) * (0.25)5 * (0.75)11 = 0.18
