Age Under 30 30 to 40 Over 40
Bachelor's degree only 90 20 40
Master's degree 10 30 10
a) What is the probability that a randomly selected accountant has only a bachelor's degree?
a) 0.5
b) 0.45
c) 0.4
d) 0.55

Answer 1

The probability that a randomly selected accountant has only a bachelor's degree is 0.45.

Step-by-step explanation:

The probability that a randomly selected accountant has only a bachelor's degree can be found by dividing the number of accountants with a bachelor's degree only by the total number of accountants. From the given data, we can see that there are 90 accountants with a bachelor's degree only out of a total of 200 accountants.

Therefore, the probability is calculated as:

P(Bachelor's degree only) = 90/200 = 0.45

So, the correct answer is 0.45 (b).
