Answer:

(b) $1.15

Step-by-step explanation:

The expected value is the sum of products of payoff and probability:

$0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05

= $0 +0.25 +0.20 +0.20 +0.50

= $1.15 . . . . expected value of the scratch ticket

kvv77 [185]

Answer: $\frac{1}{15}$

Step-by-step explanation:

Given

There are

4 country music CD

1 rock and roll CD

2 rap CD

3 Tejano CD

$\text{Probability that Jerry randomly select a Tejano CD and then a rap CD from his case}=\text{Probability of selecting a Tejano CD}\times \text{Probability of selecting a rap CD}$

$P=\frac{3}{10}\times \frac{2}{9}$

$P=\frac{2}{30}$

$P=\frac{1}{15}$

A bag contains 17 cards numbered 1 through 17. A card is randomly chosen from the bag. What is the probability that the card has

enyata [817]

Answer: 5/17

Step-by-step explanation:

Step 1: write all numbers from 1 to 17:

(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17)

Step 2: list all numbers in the space which are multiples of 3:

(3,6,9,12,15)

Probability that the card has a multiple of three of it is derived by dividing number of possible outcomes by number of total outcomes

No of possible outcomes=5

No of total outcomes =17

Pr (card drawn has multiple of 3) = 5/17

I hope this helps, please mark as brainliest answer.

emmasim [6.3K]

If there is a 22.4% chance that a soccer player will make 4 shots in a row, then the probability that he/she WON'T make 4 shots in a row is...

100 -22.4 = 77.6%

So the number of simulations that he/she will miss at least one shot in 2500 simulations would be...

2500 x 77.6% =
2500 x .776 = 1940

Clayton and Olivia played a computer game.Olivia final score was 2306421 and Clayton was 2302972.show these numbers on a number

Elden [556K]

(I cannot be the number line bit sorry)
When you're finding which one is greater, you can either write these out in words, or you can put them next to eachother.
In words- Olivia: Two million, three hundred and six thousand, four hundred and twenty one. (2306421)
Clayton- Two million, three hundred and two thousand, nine hundred and seventy two. (2302972)

From writing them out, you can see that Olivia's score has 'three hundred and six thousands', where as, Clayton has 'three hundred and two thousand'

Therefore, Olivia got the higher score.
Hope this helps :)
