Here we must see in how many different ways we can select 2 students from the 3 clubs, such that the students <em>do not belong to the same club. </em>We will see that there are 110 different ways in which 2 students from different clubs can be selected.

So there are 3 clubs:

  • Club A, with 10 students.
  • Club B, with 4 students.
  • Club C, with 5 students.

The possible combinations of 2 students from different clubs are

  • Club A with club B
  • Club A with club C
  • Club B with club C.

The number of combinations for each of these is given by the product between the number of students in the club, so we get:

  • Club A with club B: 10*4 = 40
  • Club A with club C: 10*5 = 50
  • Club B with club C. 4*5 = 20

For a total of 40 + 50 + 20 = 110 different combinations.

This means that there are 110 different ways in which 2 students from different clubs can be selected.

I need to find the area of below who can help please.
nasty-shy [4]

Triangle

Area = 1/2 b * h

Area = 1/2*15 * 9 = 1/2 * 135 = 67.5

Rectangle

Area = b * h

Area = 15 * 4

Area = 60

Trapezoid

Area = (1/2) * (b1 + b2)* h

Area = (1/2) * (15 + 18) * 4

Area = 1/2 * 33 * 4

Area = 66

Total Area

Total Area = 66 + 60 + 67.5 = 193.5 Answer
