Answer:
A: 0.1475 , B: 0.3389
Explanation:
a. Probability Refrigerator purchased from store lasts more than 15 years :
Prob(refrigerator purchase from A) and Prob(refrigerator from A life > 15 years) + .........Prob(refrigerator purchase from D) and Prob(refrigerator from D life >15 years)
(0.40x0.1)+(0.25x0.20)+(0.15x0.05)+(0.20x0.25) = 0.04+0.05+0.0075+0.05 = 0.1475
b. Refrigerator last > 15 years given , Probability it is from B :
[ Prob (B Purchase) . Prob (life > 15, given from B) ] / Prob (Life > 15)
P (B/15) = [P(B).P(15/B)] / [P15] {Bayes Theorum}
= [(0.25)(0.20)] / 0.1475 = 0.05 / 0.1475
= 0.3389
The answer would be that the answer is true
Answer:
$52,800
Explanation:
The computation of the increase or decrease in net income is shown below:
Particulars Reject Accept net income or decrease
Revenue
(6,000 × $30) $198,000 $198,000
Less:
Cost
($6,600 × ($21 + $1) $145,200 -$145,200
Net $52,800 $52,800
Since the amount comes in positive so the spcial order should be accepted
