1. Ok so first I would find 22% of 212,000 to do that you do: 22 divide 100 = 0.22
2. Now that you’ve turned 22% into a decimal as 0.22 you find what 22% of 212,000 is like so: 0.22x212,000 =46,640
3. Now that you have to reduce 212,000 but 22% to do this you just subtract: 212,000-46,640= 165,360
They would purchase the house for $165,360
Events
A = widget was produced by the old machine
B = widget was produced by the new machine.
D = widget was defective
Recall definition of conditional probability
P(X|Y)=P(X n Y)/P(Y) [ n represents set intersection operator ]
By the law of total probability,
P(A)=1/(1+3)=1/4
P(B)=3/(1+3)=3/4
Given:
Defective rate of new machine
P(D|B)=P(D n B)/P(B)=0.08 => P(D n B)=0.08*0.75=0.0600
Since P(B)=P(D n B)+P(~D n B)=0.75, this means that
P(~D n B)=0.75-0.0600 = 0.69
Proceed to calculate probability of non-defective widget given it is produced by the new machine:
P(~D|B) = P(~D n B)/P(B) = 0.69 / 0.75 = 0.92
Conclusion
The probability that the widget is not defective given that it was produced by the new machine is 0.92.
