  1. Here's how to do this.  

    chance of getting one red = 3/10 (3 red out of 10 total)

    chance of getting one green = 2/10

    chance of getting one pink is 5/10

    chance of all three happening = 3/10 x 2/10 x 5/10 = 30/1000 or 0.03 (or 3%).


  2. Isn't it?

    Probably of green = 20%

    Probably of red = 30%

    Probably of pink = 50%

  3. 3 red

    2 green

    5 pink

    =10 total marbles

    3/10 chance = red

    2/10 chance = green

    1/2 chance = pink

    1/8 chance = one of each color

    ....i think?

  4. .03%

    30%red x 20%green x 50% chance pink

    actually i take that back...i'm not entirely sure i'm right, i just sort of guessed...
