Question

A bag contains 3 white, 4 red and 5 black balls. One ball is drawn at random. What is the probability that the ball drawn is neither black nor white?

(a) 1/4

(b) 1/2

(c) 1/3

(d) 3/4

Answer 1

The probability that a ball drawn is neither black nor white from a bag with 3 white, 4 red, and 5 black balls is 1/3.

Step-by-step explanation:

The question asks for the probability that a ball drawn is neither black nor white from a bag that contains 3 white, 4 red, and 5 black balls. To calculate this probability, we first determine the total number of balls, which is 3 + 4 + 5 = 12. Next, we identify that the only remaining color that is neither black nor white is red. There are 4 red balls in the bag. So the probability is determined by dividing the number of red balls by the total number of balls. Therefore, the probability is 4/12, which simplifies to 1/3.
