Given
Electrician = 6
Mechanic = 8

Determine the probability of selecting an electrician
First, we need the total number of employees;
Next, is to determine the required probability using the following formula;
Divide numerator and denominator by 2
<em>Hence, the probability of selecting an electrician is 3/7</em>
a) because it is equal to the area of the shaded region between X=4 and X=6, and the probability that X falls within some interval is given by the area under the PDF.
b) because the shaded region is a rectangle of height 1/5 (by virtue of X following a uniform distribution over the interval [2, 7], which has length 5).
