Question

Three fair coins are tossed together. Find the probability of getting atmost one head

Sum

Solution

Three fair coins are tossed together

Sample spade = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

n(S) = 8

Let C be the event of getting atmost one head

C = {HTT, THT, TTH, TTT}

n(C) = 4

P(C) = `("n"("C"))/("n"("S")) = 4/8 = 1/2`
