Question

A company has 25 employees. Each person travels to work using only one type of transport. The probability that an employee chosen at random drives to work is 8/25. The probability that they cycle to work is 11/25. What is the total probability that an employee chosen at random either drives or cycles to work?

1) 3/5
2) 7/25
3) 19/25
4) 16/25

Answer 1

The total probability that an employee chosen at random either drives or cycles to work is 19/25.

Step-by-step explanation:

To find the total probability that an employee chosen at random either drives or cycles to work, we need to add the probabilities of driving and cycling together. The probability of driving is 8/25 and the probability of cycling is 11/25. So, the total probability is:

(8/25) + (11/25) = 19/25

Therefore, the answer is 19/25.
