Hi I need lots of help with probability 
According to the answer sheet, it seems like the integer of the denominator should be divided by 3; but I don’t get the idea how.
Thank you in advance!
Hi
that’s strange my answer is 11/52 and i divided the denominator by 6 not 3
could someone find what is wrong with my reasoning?
possible tree diagrams:
-p-g-b
-p-b-g
-g-p-b
-g-b-p
-b-g-p
-b-p-g
P (pgb) = (5 * 10 * 11)/(26 * 25 * 24) = 11/312
Ptotal = 6 * 11/312 = 11/52
