In a study of adequacy of fuel supplies C stands for the eve

In a study of adequacy of fuel supplies, C stands for the event that power place will use coal, and E is the event that it will be able to provide enough electricity. State in words the probabilities expressed by: (a) P(C\' ); (b) P(E\' ); (c) P(C E\' ). E); (f) P(C\' E); (e) P(C\' E); (d) P(C

Solution

(a) P(C\' ) : Probability that the power place will not use coal.

(b) P(E\' ) : Probability that the power place will not be able to provide enough electricity.

(c) P(CUE) : Probability that the either or both the power place will use coal and it will be able to provide enough electricity.

(d) P(C?E) : Probability that the power place will use coal and it will be able to provide enough electricity.

(e) P(C\'?E): Probability that the power place will not use coal but it will be able to provide enough electricity.

(f) P(C\'?E\' ) : Probability that the power place will not use coal and it will not be able to provide enough electricity.
