Question

McKenna is taking three people to a carnival. She will choose from 1 of her 3 cousins, 1 of her 5 neighbors, and 1 of her 2 sisters. How many possible combinations are there?

Answer 1

There are 30 possibilities.

There are 3 choices for the first person, 5 for the second and 2 from the third:
3(5)(2) = 30

Answer 2

She will choose from 1 of her 3 cousins, 1 of her 5 neighbors, and 1 of her 2 sisters.

She has to choose 1 from 3 , So here she has total 3 options available.

Then she has to choose 1 from 5 , here she has 5 options available .

And at last she has to choose1 from 2 , here she has 2 options available .

Now to find out the total number of combinations available = we multiply all the available options

So total number of possible combinations are = 3*5*2 = 30 combinations
