Marbles: You have a bag with 3 red marbles, 4 blue marbles, and 5 green marbles.

Then the probability of pulling out a red marble 3 times in a row will be

The total number of events will be

Total events = 3 + 4 + 5 = 12

The favorable event will be

Favorable event = 3

Then the probability will be

P = (3/12)(3/12)(3/12)

P = (1/4)(1/4)(1/4)

P = 1/64
