Question

A beg contains $5$ black balls, $7$ blue balls, $4$ white balls and $6$ red balls. one ball is drawn at random from the beg. Find the probability that the ball drawn is red ;

• A. $\frac{3}{11}$
• B. $\frac{6}{11}$
• C. $3$
• D. none of these

Answer 1

The correct option is A $\frac{3}{11}$

Total number of balls$=5+7+4+6=22$

Number of red balls$=6$.

Hence, probability of getting a red ball$=\frac{6}{22}=\frac{3}{11}$
