**Reiny**, Saturday, January 23, 2010 at 9:35pmyou got one marble of each colour in the jar,

so the prob of any specific colour is 1/4

a) 1/4 x 14 = 1/16

b)1/4 x 1/4 = 1/16

c) poor wording.

you are only drawing 2 marbles, so it has to be R,G or GR

Since you are replacing it would be

1/4 x 1/4 x 2

= 1/8

d) 3/4 x 3/4 = 9/16
