Aman is considering buying a one-year warranty for $100, which will cover the $600 replacement cost for his new swimming pool pump. the probability the pump does not break within the first year is 90%.

a) the expected value is −$90, so the man should not buy the warranty.
b) the expected value is $90, so the man should buy the warranty.
c) the expected value is −$40, so the man should not buy the warranty.
d) the expected value is $40, so the man should buy the warranty.

it'd me out a lot if you explained your answer!

C)The expected value is −$40, so the man should not buy the warranty.

Step-by-step explanation:

The expected value is( each value times the respective probability) minus the cost of the item

E = cost * probability + no cost * probability

   It will cost 600 dollars if it breaks * 10 percent chance it breaks

   It will cost nothing if it does not break * 90 percent chance it does not break

E = 600 * .1 + 0*90

E = 60 +0

E = 60

Now we subtract the 100 dollars for the warranty

E - 100

60-100

-40

Our expected cost is -40

C. The expected value is −$40, so the man should not buy the warranty.

May I have brainliest please? :)

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
