If two coins are tossed then the chance(probability) of getting 2 head

1.	If two coins are tossed then the chance(probability) of getting 2 heads isA) 3/4B) 1/4C) 1/2D) None
Answer» Correct option is (B) 1/4 If two coins are tossed then possible outcomes are S = {HH, HT, TH, TT} Let event E = Getting two heads = {HH} \(\therefore\) n(E) = 1 & n(S) = 4 \(\therefore\) P(E) \(=\frac{n(E)}{n(S)}=\frac14\) Hence, the probability of getting 2 heads is \(\frac{1}{4}.\) Correct option is B) 1/4

Answer»

Correct option is (B) 1/4

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

Let event E = Getting two heads = {HH}

\(\therefore\) n(E) = 1 & n(S) = 4

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

Hence, the probability of getting 2 heads is \(\frac{1}{4}.\)

Correct option is B) 1/4
