Answer:
Step-by-step explanation:
From the given information:
A sandwich shop offers eight types of sandwiches, and Jamey likes all of them equally.
The probability that Jamey picks any one of them is 1/8
Suppose
X represents the number of times he chooses salami
Y represents the number of times he chooses falafel
Z represents the number of times he chooses veggie
Then X+Y+Z ≤ 5 and;
5-X-Y-Z represents the no. of time he chooses the remaining
8 - 3 = 5 sandwiches
However, the objective is to determine the P[X=x,Y=y,Z=z] such that 0≤x,y,z≤5
So, since he chooses x no. of salami sandwiches with probability (1/8)x
and y number of falafel with probability (1/8)y
and for z (1/8)z
Therefore, the remaining sandwiches are chosen with probability
So. these x days, y days and z days can be arranged within five days in
Thus;
since 0 ≤ x, y, z ≤ 5 and x + y + z ≤ 5.
The distribution is said to be Multinomial distribution.
Since we have a cubic root, we're interested in factoring cubes inside the root, so that we can take them out. If we factor 648, we have
So, we have
And the result simplifies to
