# If Two Coins Are Tossed Once, What is the Probability of Getting: Both Heads Or Both Tails - Mathematics

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

#### Solution

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

n(s)=4

E=event of getting both heads or both tails = {HH,TT}

n(E)=2

Probability of getting both heads or both tails= (n(E))/(n(s))=2/4=1/2

Is there an error in this question or solution?
