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.)

200 =  2^3 * 5^2 * 1   =  2*2*2*5*5*1

 

No. of distinct  sequences  =

 

6! / [ No. of times 2 appears ! * No. of times 5 appears ! ]

 

6! / (3! * 2!)  =   60
