An engine encounters a standard environment with a probability of 0.9, and a severe environment with a probability of 0.1. In a

kari74 [83]

Answer:

.077

.64935

Step-by-step explanation:

Let F= failure

let S= severe

we are given that

p(F|S')= .03

p(F|S)= .5

For the first question we are looking for f

we can solve for it by using the law of total probability

so in theory we want

F∩S+F∩S'

Using the conditional probability formula we can solve for the intersections

.03*.9+.5*.1= .077

For this question we are looking for S|F

to solve this use bayes thereom

$S|F=\frac{F|S*S}{F|S*S+F|N*N}=\frac{.5*.1}{.5*.1+.9*.03}=.649$ (or 50/77)
