Question

A bag contains $2$ red, $3$ green and $2$ blue balls. $1$ ball is to be drawn randomly. What is the probability that the ball drawn is not blue?

• A. $\frac{5}{7}$
• B. $\frac{10}{21}$
• C. $\frac{2}{7}$
• D. $\frac{11}{21}$

Answer 1

The correct option is A $\frac{5}{7}$

There are $2$ red, $3$ green, and $2$ blue balls

Total number of possibilities$=7$

The possibility of the ball not being blue$=5$

$\therefore$ Probability = $\frac{5}{7}$
