Answer:
awnser is 36
Step-by-step explanation:
Y = number of yellow fish
G = number of green fish
Y = G - 6
Y = 0.40 * (Y+G)
G - 6 = 0.4*(G-6+G)
G - 6 = 0.4*(2G-6)
G - 6 = 0.8G -2.4
0.2G = 3.6
G = 3.6/0.2=18
There are 18 green fish.

Hello there!
There are 10 marbles and 2 of them are red. First pick is 2/10 to get a red and then if you pick a red marble then you have a 1/9 chance to pick a red.
So, 2/10 x 1/9 = 2/90
Simplify 2/90 to get 1/45.
Convert 1/45 to a decimal.
1/45 : 0.022222
Therefore, the probability to the nearest 10th of a percent that both marbles drawn will be red is 0.02%
