Suppose we have a bag with 10 slips of paper in it. Eight slips have a 3 on them and the other two have a 9 on them. What is the expected value of the number shown when we draw a single slip of paper? Please help me and also please don't give any links

step-by-step explanation:

oh the deck is the size of my dic k so about 320 inches hope u get my dic k as the answer

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b

its d hope this
