Answer:
Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is .
Step-by-step explanation:
From the given question, the bag contains;
$1 bill = 7
$5 bill = 1
$10 bill = 3
$20 bill = 2
Total number of bills in the bag = 13
Pulling a bill at random, the bills would have an expected value as follows:
For $1 bill, the expected value =
For $5 bill, expected value =
For $10 bill, expected value =
For $20 bill, the expected value =
Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is .
start with substituting z=e^x
then substitute u = z^(1/6):
that integral has a standard form that can be looked up in integral tables, it has the following solution:
substituting back the the variable z and then x you get the final solution:
Let 
be a probability that i-th light fails, where i=1,2,3. Then, 
is the probability that i-th light remain bright.
<span>If the lights fail independently of each other, the probability that a string of lights will remain bright for two years is:
