Question

If two identical coins are tossed, the probability of getting two heads is

 A) 1/2

B) 1/4

C) 1/6

D) 1/8

Answer 1

Correct option is (B) 1/4

If two identical coins are tossed, then possible outcomes are S = {HH, HT, TH, TT}.

Let event E be event of getting 2 heads.

\(\therefore\) E = {HH}

\(\therefore\) n(E) = 1 & n(S) = 4

\(\therefore\) P(E) \(=\frac{n(E)}{n(S)}=\frac14\)

Hence, probability of getting two heads is \(\frac{1}{4}.\)

Answer 2

Correct option is  B) 1/4
