Question

A company has 8 mechanics and 6 electricians. If an employee is selected at random, what is the probability that they are an electrician

Answer 1

`Probability = (3)/(7)`

Explanation:

Given

Electrician = 6

Mechanic = 8

Required

Determine the probability of selecting an electrician

First, we need the total number of employees;

`Total = n(Electrician) + n(Mechanic)`

`Total = 6 + 8`

`Total = 14`

Next, is to determine the required probability using the following formula;

`Probability = (n(Electrician))/(Total)`

`Probability = (6)/(14)`

Divide numerator and denominator by 2

`Probability = (3)/(7)`

Hence, the probability of selecting an electrician is 3/7
