#### Question

A man tosses two different coins (one of Rs 2 and another of Rs 5) simultaneously. What is the probability that he gets:

at least one head?

#### Solution

When two coins are tossed simultaneossly, the possible outcomes are {(H,H)(H,T)(T,H)(T,T)}

n(s)=4

The outcomes favouraable to the event E,' at least one head' aare

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

So, the number of outcomes favourable to E is 3=n(E)

Therefore, p(E)=`(n(E))/(n(S))=3/4`

Is there an error in this question or solution?
