The expected value of the game is $8.75.
----------------------
- The expected value is the <u>sum of each outcome multiplied by it's probability</u>.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- The probability of spinning a 2 and a vowel is:
. - Thus,
probability of getting $50.
- The probability of spinning 2 and a consonant is:

- Thus,
probability of getting $25.
- The probability of spinning 1 and a vowel is:
. - Thus,
probability of getting $5.
- 32 - (6 + 6 + 2) = 18, thus,
probability of earning $0.
The expected value is:




The expected value of this game is of $8.75.

Answer:
confidence interval = ( -0.38 , 0.08 )
Step-by-step explanation:
Given data :
n1 = 55 , n2 = 60 ,
Let P1 ( proportion of SUV sales at store A ) = 30 / 55 = 0.55
P2 ( sample proportion of SUV sales at store B ) = 42/60 = 0.70
The Z-value at 99% confidence Interval = 2.58
<u>Determine the 99% confidence interval for difference in proportion</u>
applying the formula below
( P1 - P2 ) ± Z ( 
Input values above into equation
confidence interval = ( -0.38 , 0.08 )
It’s 2-1=1
1-1= 0
0-1=-1
