Answer:
56.76% probability that it came from store A
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Defective.
Event B: Store A.
36% of the sales are from store A
This means that
7% of the DVD players sold at store A are defective.
This means that
Probability of a defective DVD:
36% come from store A, and of those, 7% are defective.
100 - 36 = 64% come from store B, and of those, 3% are defective. So
What is the probability that it came from store A
56.76% probability that it came from store A
The answer is there as well as the explanation on why it should go there. hope this helps if it does please mark brainliest
we have two similar triangles.
we know that in similar traingles ratios of the corresponding sides are always equal.
we have AB is propotional to PQ
BC is propotional to QR
AC is propotionbal to PR
here we dont have the lengths of sides
so the length of PR and QR will be equal to some constant have same value .
