at random. What is the probability that the ball drawn is -
(1) red. (2) not red (3) either red or white.​ from chapter probality 10 ssc​

Answer 1

The probability that the ball is red is 33.33%, it is not red 66.66%, and red or white is 66.66%.

Explanation:

Given that a bag contains 3 red, 3 white and 3 green balls, to determine, if one ball is taken out of the bag at random, what is the probability that the ball drawn is (1) red, (2) not red, or (3) either red or white, the following calculations must be performed:

1)

3/9 = 0.333 x 100 = 33.33%

2)

6/9 = 0.666 x 100 = 66.66%

3)

6/9 = 0.666 x 100 = 66.66%

Therefore, the probability that the ball is red is 33.33%, it is not red 66.66%, and red or white is 66.66%.
