1.	Three fair coins are tossed simultaneously. Find the probability of getting at least one head and a least one tail.
Answer» S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} n(S)=8 Let A: At least one head & at least one tail. A = {HTH, HHT, HTT, THH, THT, TTH}, n(A) = 6 P(A) = \(\frac{n(A)}{n(S)} = \frac{6}{8} \) = \(\frac{3}{4}\)

Three fair coins are tossed simultaneously. Find the probability of getting at least one head and a least one tail.

Answer»

S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} n(S)=8

Let A: At least one head & at least one tail.

A = {HTH, HHT, HTT, THH, THT, TTH}, n(A) = 6

P(A) = \(\frac{n(A)}{n(S)} = \frac{6}{8} \)

= \(\frac{3}{4}\)
