x/10 = 10/4x

4x^2 = 100 . . . . . cross multiply

x^2 = 25 . . . . . . . divide by 4

Pythagorean theorem = $\sqrt{a^{2} + b^2 +c^2 }$
Since you only have $a^{2}$ and $c^2$ you change the equation to $\sqrt{c^2 - a^2 = b^2}$
Giving you $\sqrt{153^2 - 72^2$ = 135

Answer:

1 - 4/9

2 - 1/9

3 - 5/9

Step-by-step explanation:

1 - Look on the left side for all two-letter combinations with only one R. We can see four. (YR, GR, RG, RY). Divide by the total number of outcomes (9).

2 - There is only one with two yellows, so divide 1 by 9.

3 - Same as before, we find 4 with 1 green and 1 with 2 green. We have to include the new one since it says atleast one. Add 1 and 4 and then divide by 9.
