A bag contains 7 red marbles, 5 blue marbles and 4 green marbles. If three marbles
are drawn out of the bag, what is the probability, to the nearest 100oth, that all three
marbles drawn will be red?

(a.13) Because I subtracted from each color. (b.14) because originally is 7 red 5 blue four green altogether the account of the marbles are 16 indirection is asked you to throw out three red so after you drop three red you are left with 5 red 5 blue 4 green

Step-by-step explanation: this is a mathematical question that could be answered and figured out multiple ways

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
