Question

If two coins are tossed once, what is the probability of getting both heads or both tails.

Answer 1

When two coins are tossed together 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`
