Answer:
25-5n/4
Step-by-step explanation:
Using the expected value of a discrete distribution, it is found that:
a) His expected value is of -$2.5.
b) The fair price of a ticket is of $0.5.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution for the net value of the ticket is:
Item a:
The expected value is given by:
His expected value is of -$2.5.
Item b:
With an unknown ticket price, the distribution is:
The game is fair if E(X) = 0, hence:
0.5 - x = 0
x = 0.
The fair price of a ticket is of $0.5.

Answer:
O
Step-by-step explanation: Just divide each kilometer by hrs for each one (sry if this doesn't make sense) O: 60 divided by 5= 12 M: 80 divided by 5=16 N: 110 divided by 5= 22. Therefore O= 12 kilometers per hour, which means its the slowest ( I did this question in khan and got it right)
Step-by-step explanation:
4 hours = 8 miles
1 hour = 8/4 = 2 miles
5.5 hours (5 hr 30 min) = 2 miles × 5.5
=11 miles
