A∩B = 212/1492 = 53/373

Step-by-step explanation:

Let the number of employees who have children is A and the number of employees who drive to work is B. Then we have these values

A = 966 / 1492

B = 488 / 1492

A or B = A ∪ B = 621/746 = 1242/1492

The question is asking the probability that an employee has children and drives to work (A∩B). Using the union formula, we can find the answer. The calculation will be:

A ∪ B = A + B - A∩B

1242/1492 = 966 / 1492 + 488 / 1492 - A∩B

A∩B = 1454/1492 - 1242/1492

A∩B = 212/1492 = 53/373
