Samples of emissions from three suppliers are classified for conformance to air-quality specifications. the results from 100 samples are summarized as follows:
conforms
yes no
supplier
1 22 8
2 25 5
3 30 10
let a denote the event that a sample is from supplier 1, and let b denote the event that a sample conforms to specifications.
(a) find p(a)
(b) find p(b)
(c) find p(b∣a)
(d) find p(a∪b)
(e) are a and 8 independent? justify your answer.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2
