Question

a
10. A bag contains 5 green, 7 red and 3 blue
balls. A ball is drawn at random. Find the
probability of drawing a red ball. If we
draw a blue ball and then a red ball, find
the sample space and the probability of
drawing a green ball.​

Answer 1

Answer:

Probability of drawing a red ball is 7/15. Probability of drawing a green ball is 5/13.

Step-by-step explanation:

There are 15 balls in total. Out of 15, 7 balls are red. So, the chance of drawing a red ball is 7/15.

There are 13 balls after the blue and red ball is drawn, therefore the chances of drawing a green ball is 5/13.
