Suppose that the time (in hours) required to repair a machine is an exponentially distributed random variable with parameter λ=0.1. What isthe conditional probability that a repair takes at least 10 hours, given that it takes more than 8 hours?

Step-by-step explanation:

Given that the time  (in hours) required to repair a machine is an exponentially distributed random variable with parameter λ=0.1.

Let X be the time taken for a repair

The conditional probability that a repair takes at least 10 hours, given that it takes more than 8 hours

= P(X≥10/x>8)

=

Parameter = 0.1

F(10) =

F(8) =

Hence answer  =0.8187

4x and 6y

im not sure though

i do not know the answer
