Question 4 Probability Exercise 25B

A bag contains 3 white and 2 red balls. One ball is drawn at random. What is

the probability that the ball is drawn is red?

a) ½

b) 2/3

c) 1/5

d) 2/5

Answer:

We know that the bag containing the total balls = 3white + 2red = 5balls

Red balls = 2

By using the formula,

Probability p () = number of favorable outcomes/ total number of outcomes

∴ Probability of getting a red ball p (R) = number of red balls/total number of balls =2/5
