In this problem there might be a number that you need to add before the "( x 3)" then your answer will be 20 = 32 - 12 = 20
Answer:
i will only answer 11 and 4
Step-by-step explanation:
4: 23 i know its not the whole thing
11:45 its not the full thing
Let A be the event 'made by Apex and defective':
P(A) = 0.67 x 0.11 = 0.0737
Let B be the event 'made by B-ink and defective':
P(B) = 0.33 x 0.06 = 0.0198
Let C be the event 'made by Apex or B-ink and defective':
P(C) = P(A) + P(B) = 0.0737 + 0.0198 = 0.0935
P(defective and made by Apex) = 0.0737/0.0935 = 0.788
The answer is 0.788 or 78.8%.
It'll be the opposite reciprocal in front of the X like instead of 3 it will be -1/3 so flip it and change the sign
