Answer & Solution
Correct Answer:
Option
D
Here S = {HH, HT, TH, TT}
Let E = event of getting at least one head = {HT, TH, HH}
$$\therefore P\left( E \right) = \frac{{n(E)}}{{n(S)}} = \frac{3}{4}$$
Let E = event of getting at least one head = {HT, TH, HH}
$$\therefore P\left( E \right) = \frac{{n(E)}}{{n(S)}} = \frac{3}{4}$$
