Answer:
The probability is 2/5 that a $20 bill will be drawn from the wallet.
Step-by-step explanation:
There are 20 total bills in the wallet (5 $5, 7 $10, and 8 $20, 5+7+8=20). So if the finder and returner of the wallet was to be given one of the bills drawn from the wallet there would be an 8/20 chance the owner of the wallet would pull a 20. That's because there are 20 total bills in the wallet and 8 of them are $20.
Simplifying 8/20... 8/20= 4/10= 2/5.
So, there is a 2/5 chance that a $20 bill will be pulled out of the wallet.
Hope this helps!
Distribute the -4. Then combine like terms.
24 - 4(5y - 6z) + 3y - 7z =
= 24 - 20y + 24z + 3y - 7z
= - 20y + 3y + 24z - 7z + 24
= -17y + 17z + 24
Answer: The first experiment has M probabilities, and the second has I(m) outcomes, that depends on the result of the first.
And lets call m to the result of the first experiment.
If the outcome of the first experiment is 1, then the second experiment has 1 possible outcome.
If the outcome of the first experiment is 2, then the second experiment has 2 possibles outcomes.
If the outcome of the first experiment is M, then the second experiment has M possibles outcomes.
And so on.
So the total number of combinations C is the sum of all the cases, where we exami
1 outcome for m = 1

2 outcomes for m=2

M outcomes for m = M
C = 1 + 2 + 3 + 4 +...´+M
To find the top and bottom circles you use:
2(pi x r^2)
- your r (radius) is half of the diameter so 3.
To find the part around it you use:
2 x pi x r x height
Circles: 2(pi x 3^2) = 56.5487
Rectangular around: 2 x pi x 3 x 5 = 94.2478
- then add them together
56.5487 + 94.2478 = 150.7965 yards^2
