Answer:

Step-by-step explanation:
We need to rationalize the denominator of
. For rationalizing we multiply the equation by 
So, solving

I think its is B. i hope you got the answer right
Step-by-step explanation:
(2160×8)÷(60×2)
Or, 270÷120
or, 2.25.
therefore answer is 2.25

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
2.
For this question we are looking for S|F
to solve this use bayes thereom
(or 50/77)
