ANSWER ASAP 1.) Suppose that 500 tickets are sold at $1.00 each for a raffle that has the following prizes: One $200 prize, Two $50 prizes, and Twenty $2 prizes. What is the expected value of a single ticket?

2.)Suppose that 10 tickets are sold for $10 each, there is one grade prize of $70. What is the expected value of a single ticket?

$2.36

Formula Used:

[n/t * (p - c)] + [(t - n)/t * (-c)] = V

V = expected $ value

n = # of tickets drawn for a prize (one prize is one drawn ticket, etc.)

t = total # of tickets

p = amount of prize money

c = cost for one ticket

Steps:

1/500(199) + 499/500(-1) = -0.6

2/500(39) + 498/500(-1) = -0.84

20/500(1) + 480/500(-1) = -0.92

(Swap signs, negative becomes positive)

0.6 + 0.84 + 0.92 = 2.36

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
