C : Percentage of workers who complete the task in more than 5 minutes = 10%
D : Percentage of workers not able to complete their task= (100-(15+65+10)) = 10%
a) Probability that a worker will be able to complete task in 5 minutes or less = 0.9
b) Probability that a worker will not be able to complete task within 4 minutes = C+D = 0.2
