Question

an URN contains 15 balls numbered 1 to 15 A ball is drawn and replaced then one more ball is drawn and replaced what is the probability that first ball drawn is odd and second is even​

Answer 1

Answer:

4/15

Step-by-step explanation:

The probability for the first ball being odd is 8/15 (as 8 out of 15 are odd numbers).

And the probability of getting the second ball as even is 7/14 (as 7 out of remaining 14 are even)

Combined:

• probability of odd and even = 8/15*7/14= 4/15

Answer is 4/15
