Answer 1

Answer

she has 27 roses, 28 tulips, 28 snapdragons and 31 daisies.

To find the possible number of bouquets she can make, she must keep in mind that the minimum number of roses is 18

So, she can have 18, 19 or 20 roses at max

This is a case of basic counting rule, but not basic multiplication rule because total number of ways of possible bouquets will be the sum of having 18 roses, 19 roses and 20 roses

18 roses + 2 other flowers

19 roses + 1 other flower

20 roses

so, she must add all the possible number of ways calculated from above three setps

option B is correct
