Bob sets two alarm clocks (battery-powered) to be sure he arises for his monday 8: 00 a.m. accounting exam. there is a 88 percent chance that either clock will wake bob. (a) what is the probability that bob will oversleep? (round your answer to 4 decimal places.)

Probability will be 0.0144

Step-by-step explanation:

We have given that the probability that there is 88 % chance that Bob wake up by either of alarm clock.

Let A Bob wake up by alarm clock 1

So P(A) = 0.88

Let B Bob wake up by alarm clock 2

So P(B) = 0.88

As we know that

Here A and B are independent events and for Bob will oversleep if both clock alarm don't wake up Bob

D

Step-by-step explanation:

10*20=200

200 + 1020= 1220

Works for the first one

20*20=400

400+ 1020=1420

Works for the second one

30*20=600

600+1020=1620

Works for the third one, and all the others one so forth.

You take the number on the left (10, 20, 30, 40, 50, 60, 70) and times it by 20, replacing the x in the equation with the number on the left side of the table. Then you add the number from said equation to result of the multiplication from the first step.
