Question

Three fair coins are tossed together. Find the probability of getting all heads

Answer 1

Three fair coins are tossed together

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

n(S) = 8

Let A be the event of getting all heads

A = {HHH}

n(A) = 1

P(A) = `("n"("A"))/("n"("S")) = 1/8`
