Question

Each number from 1 to 10 is written on a ball and the balls are put in a bag. Find the probability that the number on a ball selected at random from the bag is 3, given it is odd.4/51/41/21/5

Answer 1

Okay, here we have this:

Considering the provided information we obtain the following:

Probability that the number is 3, given it is odd=Favorable Events / Odd Events possible

Probability that the number is 3, given it is odd=1/5

Finally we obtain that the probability that the number on a ball selected at random from the bag is 3, given it is odd is 1/5 or 20%.
