Answer 2

Answer:

The probability of getting a red ball is 1/3 .

Step-by-step explanation:

• If there are n elementary events associated with a random experiment and m of them are favourable to an event A, then the probability of occurrence of A, P(A) is given by:

P(A) = number of favourable outcomes/total number of events

P(A) = m/n .

Given that:

• Box has 4 red balls and 8 white balls.
• Total number of balls present in box is 4 + 8 = 12 .
• So, total number of possible outcomes is equal to total number of balls present in box.
• n = 12 .
• Total number of red balls present in the box is 4.
• So, number of favourable outcomes of getting red ball is equal to number of red balls present in the box.
• m = 4 .
• Let, the probability of getting red ball is denoted by P( red ), then:
• P( red ) = 4/12 = 1/3.
• Hence, probability of getting red balls is 1/3.
