from the question, we were told that the probability of Levente passing each of the module is 0.78

therefore,

a) the probability of Levente passing all three modules is

= 0.78^3

= 0.47

b) the probability of Levente passing two of the modules is

= (0.78^2)(1 - 0.78)

= (0.6084)(0.25)

= 0.15

c) the probability of Levente passing none of the modules is

= (1 - 0.78)^3

= (0.25)^3

= 0.015
