Plzz help me to find coefficient in binomial theorem (25 points)

Viefleur [7K]

Denote x2 by y. 

 

(x2-3)7=(y-3)7 

 

This is a binomial expansion in y, and you want the coefficient of y4 because y4=x8 

 

You have 7 terms of (y-3) in (y-3)7. To get the fourth power of y, you need to choose y from four of the terms. The number of ways you can do this is the combinations of 7 things taken 4 at a time. This is:

 

7!/(4!3!)=35

So, the coefficient of x8 in the given expansion will be 210.

A) There are 100 students who play at least one of volleyball, soccer and hockey, of these 50 play au three games, 84 play socce

Scilla [17]

Answer:

Step-by-step explanation:

Let H be the set of students who play Hokey

V be the set of students who play Volleyball

S be the set of students who play Soccer

======================================

card(volleyball only) = card(V) - [card(V∩H∩S) + card(V∩H only) + card(V∩S only)]

= 73 - [50 + (58-50) + (62-50)]

= 73 - [50 + 8 + 12]

= 73 - 70

= 3

………………………………………………

Card(Hokey only) = 100 - [3 + 8 + 50 + 10 + 12 + 12]

= 100 - 95

= 5

…………………

Note :

A Venn diagram might be helpful in such case.
