If three different coins are tossed together, then find the probability of getting two heads.

Question

Philoid · Accepted Answer

Let H denote the event a head is obtained, T denote the event a tail is obtained

When three different coins are tossed together the sample spaces created are:

{(H,H,H),(H,H,T),(H,T,H),(T,H,H),(H,T,T),(T,H,T),(T,T,H),(T,T,T)}

Favorable outcomes of getting two heads =

{(H,H,T),(H,T,H),(T,H,H)}

Total number of favorable outcomes = 3

Total number of outcomes = 8

Answer: The Probability of getting two heads
