Answer:
4.4722
Step-by-step explanation:
The following table shows the 36 elements of the sample space of the experiment
From this table we can compute the probabilities
:
P(X = 1) = 1/36
P(X = 2) = 3/36
P(X = 3) = 5/36
P(X = 4) = 7/36
P(X = 5) = 9/36
P(X = 6) = 11/36
So the expected value equals
1P(X=1)+2P(X=2)+3P(X=3)+4P(X=4)+5P(X=5)+6P(X=6) =
= 1/36 + 6/36 + 15/36 + 28/36 + 45/36 + 66/36 = 161/36 =
4.4722
This turns out to be a division problem. To find how many each person can get, you must divide the amount of food by how many guests.
126 divided by 21 is 6
84 divided by 21 is 4
Each guest will get 6 chocolate truffles and 4 caramel truffles.

2)0.25
3)0.083
Step-by-step explanation:
1 is just 3/6
2 is 3/6*1/2
3is 1/6*1/2
