the question

A sample space contains 10 simple events, E1, E2, E3, ..., E10. In each case list the proba- bilities of the 10 simple events. (a) The simple events have equal probabilities. (b) P(E1) = P(E2) = P(E6) = P(Es) = 0.1, P(E3) = P(E;) = P(Eg) = 0.16, P(EA) = P(E-) = P(E10) =? (c) P(E1) = 0.45, 3P(E2) = 0.45, and the other eight events have equal probabilities
