Question 8Levente is taking three modules this semester as part of his foundation year ofComputer Science degree. The probability of Levente passing each of the modulesis 0.78. Calculate the probability of Levente passing:a) All the three modules;b) Two of the modules;c) None of the modules.nuention

Sagot :

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
