The probability that a randomly selected worker contributes to a retirement savings plan at work is male is 0.484.
How to determine the value of the probability
From the question, we have the following parameters that can be used in our computation:
The table of values
Let C represent that the selected employee participates to a workplace retirement savings plan.
Let M stand for the male employee.
From the table of values, we have the following
C n M = 121
M = 250
The probability that a randomly selected worker contributes to a retirement savings plan at work is male is calculated using
P(C | M) = P(C n M)/P(M)
Substitute the known values into the equation
P(C | M) = 121/250
Evaluate
P(C | M) = 0.484
Hence, the probability is 0.484.
