## Main Question or Discussion Point

Three people are selected at random. Find the probability that

(a) all three share the same birthday:

(365/365)(1/365)(1/365) = 0.00000751

(b) none of the three shares the same birthday. Assume 365 days in a year.

(365/365)(364/365)(363/365) = 0.992

(a) all three share the same birthday:

(365/365)(1/365)(1/365) = 0.00000751

(b) none of the three shares the same birthday. Assume 365 days in a year.

(365/365)(364/365)(363/365) = 0.992
