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?
