A coin is tossed twice. If the outcome is at most one tail, what is the probability that both head and tail have appeared?

Solution: Given a coin is tossed twice

Then the sample space will be

Given that the outcome is at most one tail

So favourable outcomes will be

Let be the event of getting at most one tail


Probability of to happen is

Let   be the event that both head and tail had appeared 

then the outcomes of is


Probability of to happen is

Favourable outcomes of is



Required probability is the probability of given that has happen

As we know that


So Probability that both head and tail have appeared if the the outcome is at most one tail is
