Answer:
10
Step-by-step explanation:
5 choose 2 is 5x4/2, which is 20/2, which is 10.
The number of different pairs of fruit that John could bring to school is 10 given that he has an apple, an orange, a pear, a banana, and a kiwi at home. This can be obtained by using combination formula.
Combination is grouping of items,
⇒ ⁿCₓ = [tex]\frac{n!}{(n-r)!r!}[/tex] ,
where n is the number of items and r is number of selected items
Given that there are 5 fruits and number of fruits that can be selected is 2.
Thus, n = 5 and r = 2
ⁿCₓ = ⁵C₂ = 5!/[(5-2)!2!] =5!/[3!2!] =120/12 =10
There are 10 different possible pairs of fruits.
Hence the number of different pairs of fruit that John could bring to school is 10 given that he has an apple, an orange, a pear, a banana, and a kiwi at home.
