A fair die is rolled 4 times in succession. What is the probability that the number on each roll is strictly less than the numbe

svetlana [45]

The number of such results in which each number is not less than the previous number will be equal to the number of ways of choosing 4 numbers out of 6 with replacement; regardless of order!

Why?

the probability that the number on each roll is strictly less than the number on the previous roll is 7/72

Let us choose any such set of size 4, say {2, 1, 1, 3}. we can sort it to get the sequence {1,1,2,3}, which is one of our desired results. Thus, each sequence ordered in this way corresponds to one selection of size 4, with replacement and regardless of order.

The number of such selections will be equal to the number of solutions to the following equation:

x1 + x2 + x3 + x4 + x5 + x6 = 4

where:

x1: number 1 in selections

x2: number of 2s in selection

x6: number of 6s in selection

The number of unique solutions of such an equation = 9, choose 5 = 126

(See: Unordered sampling with replacement for more details on this)

Number of possible outcomes = 6^4 = 1296

Probability of favorable results = 126/1296=7/72

Alison set aside $55 each month to spend on books and cd .If she spends c dollar on cds given a month she may spend b dollar on

WINSTONCH [101]

For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:
b = 25
