Catherine rolls a standard 6-sided die six times. If the product of her rolls is 200, then how many different sequences of rolls could there have been? (The order of the rolls matters.)

*Catherine rolls a standard 6-sided die six times. If the product of her rolls is 200, then how many different sequences of rolls could there have been? (The order of the rolls matters.)*

The prime factorization of 200 is 2 x 2 x 2 x 5 x 5 but

that's only five factors and Cat rolled six times so we

need to add a 1 to the rolls.

She had to roll these numbers: 1, 2, 2, 2, 5, 5

How many sequences of these could have occurred.

The permutation of six things taken six at a time.

_{6}P_{6} = 720

Oh, she could have rolled 1, 1, 4, 2, 5, 5 etc.
