00:00:00.820 --> 00:00:04.300
The table shows the number of employees in each department of a company.
00:00:04.830 --> 00:00:10.100
If an employee is selected at random, what is the probability that they are part of the sales department?
00:00:10.630 --> 00:00:13.690
Here we can see that there are two employees in the sales department.
00:00:14.290 --> 00:00:22.560
The probability of being in the sales department will be the number of employees in sales divided by the total number of employees.
00:00:23.120 --> 00:00:25.890
So we know that there are two employees in sales.
00:00:26.430 --> 00:00:38.860
Now to find the total, there are five in marketing, eight in finance, 25 in customer service, six in warehouse, four in IT, and two in sales.
00:00:38.860 --> 00:00:42.900
So now to find our denominator, we need to add these numbers together.
00:00:43.380 --> 00:00:44.370
And we get 50.
00:00:44.990 --> 00:00:48.080
So the probability of being in the sales department is two out of 50.
00:00:48.110 --> 00:00:49.620
However, we need to reduce.
00:00:50.590 --> 00:00:55.770
Two goes into two and two also goes into 50, resulting in one twenty-fifth.
00:00:56.380 --> 00:01:03.870
Therefore, if an employee would be selected at random, the probability that they’re in the sales department would be one twenty-fifth.
