5. To prevent a flooded basement, a homeowner has installed two special pumps that work automatically and independently to pump
1 answer:
Answer:
The probability that both pumps will fail to work at the same time is 0.025 or 2.5%.
Step-by-step explanation:
The probability that both pumps will fail to work at the same time is the multiplication of the probabilities that the pomps fail.
That is
- the probability that the old pump fail =
- the probability that the newer pump fail =
Then, the probability that both fail at the same time is:

- - Lets solve for G.
Keep in mind: G is acting as a unknown variable, commonly used as "x"
So we need to find the variable, and then we solve for g until we get "0" for our problem.
Okay so lets start off by factoring our equation, in this case you do left first.
Alright, now we can set out "o" as the equal to all of our factors.
And now you need to solve for that,
And you get -1 for our answer.
Final answer: g=-1
