melamori03 [73]

Answer:

The probability of being a male and a satisfied employee is 27%

Explanation:

The probability of being a male P(m) = 60% = 60/100 = 0.6

The probability of being a satisfied employee P(s) = 45% = 45/100 = 0.45

Mathematically, the probability of being a male and satisfied = Probability of being a male * Probability of being a satisfied employee = P(m) * P(s) = 0.6 * 0.45 = 0.27

or simply 27/100 which is same as 27%
