<h2>The chances of receiving two greens are 5/31.</h2>
<em>Given a bag containing four blue, three red, and five green marbles, the total result is:</em>
<em>Total number of balls = 4 + 3 + 5 = 12</em>
<em>If green is chosen first, the chances of picking a green are 5/12.</em>
<em>The probability that the second stone is green is 4/11 if it is picked and not replaced (4 greens remaining)</em>
<em>The chance of earning two greens is 5/12 4/11.</em>
<em>The chance of getting two greens is 20/132.</em>
<em>The chance of earning two greens is 5/31.</em>
<h3>
<em>As a result, the chance of getting two greens is 5/31.</em></h3>
The common factor is 2 so: 2(4x+3) is the answer
If the weight of the little brother is x, then the weight of Charles is x + 9
The equation that can be used to determine what each one weighs is:
x + (x + 9) = 99.
Let us now solve it.
x + x +9 = 99
2x + 9 = 99
2x = 99 - 9
2x = 90
x = 90/2
x = 45
Little brother's weight is 45 kg.
Charles' weight will be 45 + 9 = 54 kg
Adding these two weights will give 99kg
