Answer:

630 distinct possible collections of letters could be put in the bag.

Step-by-step explanation:

Since on the refrigerator, MATHCOUNTS is spelled out with 10 magnets, one letter per magnet, and two vowels and three consonants fall off and are put away in a bag, if the Ts are indistinguishable, to determine how many distinct possible collections of letters could be put in the bag, the following calculation must be performed:

Vowels: 3

(AO, AU, OU)

Consonants: 7

3 x 7 x 6 x 5 = X

3 x 210 = X

630 = X

Therefore, 630 distinct possible collections of letters could be put in the bag.
