At a raffle, 1500 tickets are sold at $2 each. There are four prizes given for $500, $250, $150, and $75. You buy one ticket. Us

Answer:

<u>The expected value of every ticket is a loss of $ 1.35</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of tickets sold at the raffle = 1,500

Price of each ticket = $ 2

Total prizes = 1 * $ 500 + 1 * $ 250 + 1 * $ 150 + 1 * $ 75

2. Use a probability distribution table to calculate the expected value of your gain. Your expected value is_____ ?

Let's answer the question using a probability distribution for the gains, this way:

Probability of 1st prize of $ 498 (500 - ticket) = 1/1,500
Probability of 2nd prize of $ 248 (250 - ticket) = 1/1,500
Probability of 3rd prize of $ 148 (150 - ticket) = 1/1,500
Probability of 4th prize of $ 73 (75 - ticket) = 1/1,500
Probability of losing $ 2 (ticket) = 1,496/1,500

Now, we calculate the mean for all the tickets (winners and non-winners), this way:

Expected value = [(1,496 * -2) + (1 * 498) + (1 * 248) + ( 1 * 148) + ( 1 * 73)]/1,500

Expected value = [- 2,992 +498 + 248 + 148 + 73)/1,500

Expected value = -2,025/1,500 = - 1,35

<u>The expected value of every ticket is a loss of $ 1.35</u>

A circular playground for a daycare center is to be covered with square tiles that are 9 inches on each side. The circle has a d

nydimaria [60]

Answer:

9 boxes

Step-by-step explanation:

$Area=\pi r^{2}$

Since 1 ft= 12 inches then with diameter of 12 ft, radius becomes 6 ft and converted to inches it's 6*12=72 in

$Area=\pi\times 72^{2}=16286.01632 in^{2}$

Area of 1 tile= 9*9=81

Number of tiles= $\frac {16286.01632
}{81}=201.0619298
\202 tiles$

Number of boxes= 202/25=8.08 boxes hence 9 boxes

To find the mean add up all the numbers given then divide your answer by how many numbers there are.
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3
