If you ask three strangers about the day they were born,What is the probability number of born on a Saturday?

THERE ARE TOTAL 52 SATURDAYS IN A YEAR

365-52 = 313 ARE NON SATURDAYS

PROBABILITY OF SATURDAY = 52/365 = 0.142

PROBABILITY OF NON SATURDAY = 0.858

CASE 1 = 1 BORN ON SATURDAY = 3C1*(0.142)*(0.858)^2 = 0.313

CASE 2 = 2 BORN ON SATURDAY = 3C2*(0.142)^2(0.858) = 0.051

CASE 3 = 3 BORN ON SATURDAY = 3C3*(0.142)^3*(0.858)^0 = 0.002

ADD ALL THE CASE PRBABILITY = 0.313+0.051+0.002 = 0.366
