Answer:

The Probability of both male and rides the bus is P(x , y) =  0.0644

Step-by-step explanation:

Given data

Males responded x = 0.23

The male respondents ride the bus y = 0.28

Probability of both male and rides the bus is given by

P(x , y) = x × y

Put the values of x & y in equation (1) we get

P(x , y) = 0.23 × 0.28

P(x , y) =  0.0644

Therefore the Probability of both male and rides the bus is P(x , y) =  0.0644
