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

The word difference means subtract

Answer:
It is A
Step-by-step explanation:
Got it right on the test :)
3x -1 = 11
3x = 11 + 1
3x = 12
x = 4
I take it by, x2 + x, you mean 2x + x, since x = 4, then
2x + x = 2(4) + (4) = 8 + 4 =12
