Answer:
Answer is
a. P (both pumps not available) = 0.016
b. P (both pumps available) = 0.984
Step-by-step explanation:
a. Probability of neither pump is available.
We know that P1 + P2 = 1
P1 = Probability of one pump is available = 0.96
P2 = Probability of a pump not available = 1-0.96 = 0.04
Now the probability of both pump not available will be = P2 x P2
=0.04 x 0.04 = 0.016
b. Probability of both pumps available will be.
Using the equation of probability
P (both pumps available) + P (both pumps unavailable) = 1
P (both pumps available) = (1- P (both pumps unavailable))
P (both pumps available) = 1-0.016
P (both pumps available) = 0.984
To add the bushes and trees, to get 19 bushes and 6 trees, but this wouldn't get me anywhere, because I don't have subtotals for the bushes and trees.
So I'll pick variables (b for the number of bushes and t for the number of trees) and set up a system of equations:
first order: 13b + 4t = 487
second order: 6b + 2t = 232
Multiplying the second row by –2, I get:
13b + 4t = 487
–12b – 4t = –464
This says that b = 23.
Back-solving, I get that t = 47.
Of course, the exercise didn't ask for the values of the two variables. Translating back into English, the solution is,
each bush is $23 and each tree is $47.
