Answer:
First, we have two marbles, and i guess that each one has the same probability of being picked at random (actually they have different densities, so one may have a larger probability than the other).
The possible outcomes are:
S G
S S
G S
G G
Now, suppose that we want to find the probability of the S G outcome.
In the first selection, we want to pick the silver marble, with a probability of ps,
In the second selection, we want to pick the gold marble, with a probability pg
As the events are independent, the joint probability will be equal to the product of the probabilities for each selection:
P = ps*pg
Now, if both marbles have the same probability of being picked, then:
ps = 0.5
pg = 0.5
P = 0.5*0.5 = 0.25
And this will be the same for each outcome.
Answer:
You would need about 13 eggs.
Step-by-step explanation:
216 cookies would be taking the original recipe and making 4 and a half batches. So we multiply 3 by 4.5 to get 13.5.
Answer:
60/100 divided by 2
Step-by-step explanation:
60%= 60/100
100 divided by 2 is <u>50</u>
( what you do to the top you do to the bottom)
60 divided by 2 is 30
60/100= 30/50
So the answer is 30
<h2>HOPE THIS HELPS o(≧o≦)o ◑﹏◐</h2>
Answer:
671 miles.
Step-by-step explanation:
The number of times the sun will rise in two years will be measured in the number of days in those two years assuming that the location is far enough from the poles that the length of days and nights are relatively the same.
If neither of the two consecutive years is a leap year, then the number of times the sun will rise in two years will be:
2 (365) = 730 times
If one is a leap year, then the number of times the sun will rise in two years will be:
2 (365) + 1 = 731 times
