b)The probability that a drilling operation will be a success is 0.34 and the probability that it will not be a success is -0.66.

a) There are only two possibilities: silver or no silver. The probabilities must sum to 1. In this example, they sum to 0.90.
b) Again the probabilities must sum to 1 and probabilities must be greater than or equal to zero and less than or equal to 1. Negative values are excluded.
