If two events are dependent on each other you have to multiply the probability of the first event times the probability of the second event.
first count all the marbles here there are 21
you are asked about picking two green marbles there are 7 out of the 21 total.
The first event would be 7/21
The second event would be 6/20 (since you didn't replace and you took out a green one)
now multiply your two fractions together:
and you get 1/10.
Answer:
a. h2400 b.33600 c.1.5
Step-by-step explanation:
a.
2400 skiers per hour
then in h hours h x 2400 skiers
b.
in 14 hours 14x2400=33600 skiers
c.
to move 3600 skiers we need 3600/2400=1.5 hours
Using the expected value, it is found that the mean of the distribution equals $0.1.
- The expected value, which is the mean of the distribution, is given by <u>each outcome multiplied by it's probability</u>.
The probabilities of <u>each outcome</u> are:
- .0000001 probability of earning $1,000,000.
- .9999999 probability of earning $0.
Thus, the mean is given by:

Thus showing that the expected value is $0.1.

Answer:
D. 8
Step-by-step explanation:
2p=16
divide both sides by 2 to get p alone
p=8
4315
<u>+5684
</u> 9999 So 5684 is the greatest number you can write.<u>
