#### Question

If two coins are tossed once, what is the probability of getting:

#### Solution

When two coins are tossed together possible number of outcomes= {HH,TH,HT,TT}

n(s)= 4

E= event of getting at least one head ={HH,TH,HT}

n(E)=3

Probability of getting at least one head = (n(E))/(n(s))=3/4

Is there an error in this question or solution?
