Question

Two coins tossed together. What is the probability of getting at least one head?

• A. $\frac{1}{4}$
• B. $\frac{1}{2}$
• C. $\frac{3}{4}$
• D. $1$

Answer 1

The correct option is C

$\frac{3}{4}$

Total possible outcome = {HH, HT, TH, TT} (H = Heads, T = Tails)

= 4

Number of favourable outcomes = {HH, HT, TH}

= 3

$\text{Probability to get at least one head}=\frac{\text{Favourable outcomes ( at least one head)}}{\text{Total possible outcomes}}$

=$\frac{3}{4}$
