Question

A bag contains $20$ brown and $20$ red balls. One ball is drawn at random. What is the probability that ball is red?

• A. $\frac{1}{5}$
• B. $\frac{3}{2}$
• C. $\frac{1}{2}$
• D. $\frac{3}{5}$

Answer 1

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

Total number of balls $=20+20=40$
$P$ (red balls) $=$ $\frac{20}{40}=\frac{1}{2}$
