slega [8]

A. How many different selections are possible?

B. What is the probability of winning?

C. If you win, what is your net profit?

D. Find the expected value

Answer :

A. sequence of three digits (from 0 to 9). so 10 numbers.

We know 3 lottery games. So possible selections = 10^3 = 1000

B. Probability of winning = one outcome / total outcomes

P( winning) = $\frac{1}{1000}$ = 0.001

c. Net profit = winning amount - paid amount

= 384.13 - 1.33 = $382.8

D. expected value

E(x) = net profit * winning probability - paid amount * lost probability

E(x) = 382.8 * 0.001 - 1.33 * 0.999 = -0.95

you expect to lose 95 cents per ticket.

Ayden is making smoothies. Each smoothie needs 1/4 cups of yogurt. He has 2 1/2 cups of yogurt. How many smoothies can he make?

Mumz [18]

Answer:

Ayden can make 10 smoothies

Step-by-step explanation:

1 cup of yogurt would be equal to four 1/4 cups.

2 cups of yogurt would be equal to eight 1/4 cups.

1/2 cup of yogurt would be equal to two 1/4 cups.

If two cups of yogurt equals eight 1/4 cups and 1/2 cup equals two 1/4, Ayden would be able to make 10 smoothies with the amount he has.

I’m having trouble on my last one

Nadya [2.5K]

Answer: 52

Step-by-step explanation:

First, divide 13 by the total amount of shows, 19. Then, divide 76 by 19. This results in 4, which when multiplied by 13, results in 52. To check the answer just divide 52/76 and you should get the same number as with 13/19.
