WINK, Inc. follows a certain procedure that requires two tasks to be finished independently in order for a job to be done. On any given day, there is a 7/8 probability that task 1 will be completed on time, and a 3/5 probability that task 2 will be completed on time. On a certain day, what is the probability that task 1 will be completed on time, but task 2 will not?

答案
D
解析
Task 1 has a 7/8 probability of being completed on time, and task 2 has a 3/5 probability of being completed on time, which can also be expressed as a 2/5 probability of not being completed on time, which is what the problem asked for. Multiply the probabilities and we get
which reduces to 7/20.
