Question

If we draw a ball from an urn containing 10 numbered balls, with seven red balls that are numbered 1, 2, 3, 4, 5, 6, 7 and three that are green and are numbered 8, 9, 10, what is the probability of drawing a ball that is red and odd?

Answer 1

Step-by-step explanation:

Total balls = 10

Odd red balls = 1 3 5 7 so 4 balls

Probability of odd and red ball = 4/10 = 2/5
