Question

A basket of 40 pairs of pliers at a discount hardware store includes 5 pairs of 6-inch pliers. A second basket contains 20 hammers, including 3 large hammers. What is the probability of drawing a 6-inch pair of pliers from the first basket without looking?

Answer 1

First, add all the numbers together, which is 68. Then divided 100 by 68, which gives you the number 1.47, and that's your answer.

Answer 2

Answer: Our required probability is
`(1)/(8)`

Explanation:

Since we have given that

Number of pairs of pilers = 40

Number of pairs of 6-inch pilers = 5

So, Probability of drawing a 6-inch pair of pilers from the first basket without looking is given by

`\frac{\text{Number of favourable outcome}}{\text{ Total number of outcomes}}\\\\=(5)/(40)\\\\=(1)/(8)`

Because in another basket of hammers, there is no pilers.

Hence, our required probability is
`(1)/(8)`
