Question

Given a population comprised of 30 bats, 15 gloves, and 60 balls, if sampling is random and one at a time without replacement, what is the probability of obtaining a bat and a ball in that order if two objects are sampled from the populationGroup of answer choices

Answer 1

The probability would be 3/125 in the given conditions.

As there are 105 items, of which 30 are bats. The probability for that draw is 30/105.

There are now 104 items remaining, of which 15 are gloves. The probability of getting a glove now is 15/104.

There are now 103 items remaining, of which 60 are balls. The probability of getting a ball now is 60/103.

The probability of all three occurring = product of three

15/104* 30/105* 60/103

= 3/125

Hence the probability is 3/125.
