Answer:
The probability that the product will be successfully launched given that the market test result comes back negative is 0.30.
Step-by-step explanation:
Denote the events provided as follows:
<em>S</em> = a product is successfully launched
<em>P</em> = positive test market result
The information provided is:
P (S) = 0.60
P (P | S) = 0.80
P (P | S') = 0.30
Then,
P (P' | S) = 1 - P (P | S) = 1 - 0.80 = 0.20
P (P' | S') = 1 - P (P | S') = 1 - 0.30 = 0.70
Compute the probability of positive test market result as follows:
The probability of positive test market result is 0.60.
Then the probability of negative test market result is:
P (P') = 1 - P (P)
= 1 - 0.60
= 0.40
Compute the probability that the product will be successfully launched given that the market test result comes back negative as follows:
Thus, the probability that the product will be successfully launched given that the market test result comes back negative is 0.30.
Answer:
3 French horns
6 tubas
9 trumpets
Step-by-step explanation:
Let the number of French horns be x.
<u>Number of French horns</u> = x
There are twice as many tubas as French horns, so
<u>Number of tubas</u> = 2x
There are three more trumpets than tubas, so
<u>Number of trumpets</u> = 2x + 3
Five times the number of trumpets equals nine times the number of French horns, plus triple the number of tubas, so
