Question

please tell me how to solve this.......​

Answer 1

Answer:

Total number of balls in the bag = 10.

1. Number of black balls = 5

Probability of picking a black ball = 5/10 = 1/2

2. Number of red balls = 2

Probability of picking up a red ball = 2/10 = 1/5

3. Number of white balls = 3

Probability of picking up a white ball = 3/10

4. Probability of not picking a red ball = 10- 2 / 10

= 8/10 = 4/5

5. Probability of not picking up a black ball = 10-5/10 = 5/10 = 1/2
