Question

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

both heads

Solution

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

n(s)=4 

E= event of getting both heads= {HH} 

n(E)=1 

Probability of getting both heads= `(n(E))/(n(s))=1/4 ` 

  Is there an error in this question or solution?
