A box contains 14 balls (10 red and 4 white). Three balls randomly drawn out of the box. Determine the following probabilities:
P(three red balls)=
P(two red and one white)=
P(one red and two white balls)=
P(three white balls)=

• finite math -

You didn't say if the balls are returned, but in most of these type of questions, they would not be returned
I will assume they are not returned to the box.

Prob(3 red) = (10/14)(9/13)(8/12) = ...

Prob(2 red, one white)
could be RRW, RWR, WRR
prob = 3(10/14)(9/13)(4/12) = ....

Study my method I used above, then apply the same method to the last two.
