Aggregates for the construction of a reinforced concrete building are supplied by two companies, Company A and Company B. Orders are for Company A to deliver 700 truck loads a day and 300 truck loads a day from Company B. From prior experience it is expected that 5% of the material from Company A will be substandard and 3% of the material from Company B will be substandard. Part 1 What is the probability of substandard aggregates

The probability of substandard aggregates is 0.044.

Step-by-step explanation:

We are given that orders are for Company A to deliver 700 truckloads a day and 300 truckloads a day from Company B.

From prior experience, it is expected that 5% of the material from Company A will be substandard and 3% of the material from Company B will be substandard.

Let the probability that orders are for Company A to deliver = P(A) =

The probability that orders are for Company B to deliver = P(B) =

Let event S = material which is substandard

So, the probability that the material from Company A will be substandard = P(S/A) = 0.05

the probability that the material from Company B will be substandard = P(S/B) = 0.03

Now, the probability of substandard aggregates is given by = P(S)

P(S) = P(A) P(S/A) + P(B) P(S/B)

      = 0.7 0.05 + 0.3 0.03

      = 0.044

Hence, the probability of substandard aggregates is 0.044.

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
