Question 41 Probability Exercise 13.1

A bag contains 5 white balls and 7 red balls. One ball is drawn at random. What is the probability that ball drawn is white?

Answer:

Solution:

The possibility that an event will occur is referred to as the probability of the event. In mathematics, this possibility of an event happening is represented by a number between 0 and 1.

Given: A bag contains 7 red and 5 white balls and a ball is drawn at random

Required to find: Probability that the ball drawn is white

Total number of balls 7 + 5 = 12

Total number of white balls is 5

We know that Probability = Number of favourable outcomes/ Total number of outcomes

Thus, the probability of getting a white ball = 5/12
