Question

Suppose you want to rearrange 6 flowers in a flowers bed, if you have 10 types of flowers to choose from, how many different ways can you arrange them?

Answer 1

Order counts, so it is a permutation 6 from 10, 10 P 6 = 151,200

Answer 2

Permutation = order counts
Combination = order does NOT count

Answer 3

If two dice are rolled what is the probability of obtaining a sum less than 6?

Answer 4

There are 36 possible outcomes when rolling two dice.

If you want the sum to be less than 6, the rolls must be either:

((1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (3,1), (3,2), (4,1)

Therefore, the probability is 10/36 or 5/18 reduced.

Answer 5

Thanks.
