Question

The probability of getting at least two heads when tossing a coin three times is

• A. $\frac{1}{4}$
• B. $\frac{1}{3}$
• C. $\frac{1}{2}$
• D. $\frac{1}{8}$

Answer 1

The correct option is C $\frac{1}{2}$

For getting at least two heads when tossing a coin three times is $=(H,H,H),(H,H,T),(H,T,H),(T,H,H)$
The probability $=4/8=1/2$
