Kyle, David, and Catherine each try independently to solve a problem. If their individual probabilities for success are 1/8, 1/4 and 3/5, respectively, what is the probability no one will solve the problem?
Choose the most appropriate option:
A) 3/80  B) 21/80  C) 5/16  D) 25/76  E) 9/80
P(Kyle will not solve)=1 - 1/8 = 7/8   P(David will not solve)= 1 - 1/4 = 3/4   P(Catherine will not solve) = 1- 3/5 = 2/5   P= (7/8)*(3/4)*(2/5) = 42/160 = 21/80   Answer:21/80
