Of the 8 students in the chess club, three will represent the club at an upcoming competition. How many different 3-person teams

xz_007 [3.2K]

I think that this is a combination problem. From the given, the 8 students are taken 3 at a time. This can be solved through using the formula of combination which is C(n,r) = n!/(n-r)!r!. In this case, n is 8 while r is 3. Hence, upon substitution of the values, we have

C(8,3) = 8!/(8-3)!3!
C(8,3) = 56

There are 56 3-person teams that can be formed from the 8 students.

Rolling 7 or 11 on the first roll is a win probability of winning on 1st roll

gtnhenbr [62]

1/6 plus 1/18, which equals to 2/9. Suppose we roll 4 on the first roll (the probability of rolling 4 is 1/12). On each successive roll the probability of rolling 7 is 1/6 and the probability of rolling 4 is 1/12.

[i.dk how this can help but if you got a 7 or 11 rolling on the first round you would probably win]

Each year Lizzie’s school purchases student agenda books, which are sold in the school store. This year, the school purchased 35

Stells [14]

The school can charge $7.54 for each agenda book.

Step-by-step explanation:

Given,

Purchase price of 350 books = $1137.50

Profit they want to make = $1500

Total amount = 1137.50 + 1500 = $2637.50

Therefore;

The school must sell 350 books for $2637.50

Thus,

350 books = 2637.50 dollars

1 book = $\frac{2637.50}{350}$

1 book = $7.535

Rounding off to nearest cent

1 book = $7.54

The school can charge $7.54 for each agenda book.
