Help, please!! There are 32 pieces of building blocks in a bag: 8 each of blue, green, red, and yellow. Four pieces are chosen at random. Identify the probability that all 4 of the pieces are red.

OpenStudy (meehan98):

My options are: 6/4356 6/3596 7/3596 7/899

OpenStudy (meehan98):

I'm sorry, but I'm confused by that. How did you get 24?

OpenStudy (meehan98):

Okay.

OpenStudy (madhu.mukherjee.946):

your correct answer will be 8c4/32c4

OpenStudy (madhu.mukherjee.946):

that will give you 70/35960=7/3596

OpenStudy (madhu.mukherjee.946):

yeah this one is perfect

@Meehan98

OpenStudy (meehan98):

okay, so how did you get 70/35960? I'm doing something wrong with: 8c4/32c4. I keep getting 14/35960?

OpenStudy (meehan98):

Ah! Never mind! I forgot to multiply by five! Thank you!!!
