A game has 6 certain number of blue, red or black tokens. If you draw a token at random, the odds of getting a blue token are 1:2 and and the odds against getting a red token are 5:1.

a) If there are 32 blue tokens in this game, how many chips are there altogether?

b) If a against token is drawn at random, what are the odds of getting a black token ?

If there are 32,y,z blue, red, black tokens, respectively,
32/(y+z) = 1/2
(32+z)/y = 5/1
Now you should be able to answer the questions (if you can figure out what (b) actually means)
Sorry didnt get it and i got confused for both parts.
solve those equations and you find that there were
32 blue, 16 red, 48 black

you shouldn't have any trouble now with the questions ...
