Vedclass · Answer

(A) Total number of balls = $40$.Number of red balls = $18$.Number of yellow balls = $12$.Number of blue balls = $	ext{Total balls} - (	ext{Red balls} + 	ext{Yellow balls}) = 40 - (18 + 12) = 40 - 30 = 10$.The probability of drawing a blue ball is given by the ratio of the number of blue balls to the total number of balls.$P(	ext{Blue}) = \frac{	ext{Number of blue balls}}{	ext{Total number of balls}} = \frac{10}{40} = \frac{1}{4} = 0.25$.

$A$ bag contains $40$ balls of the same shape and weight. Among the balls, $18$ are red, $12$ are yellow, and the rest are blue. What is the probability that a ball drawn at random from the bag is blue?
