The probability that the marbles selected are of the same colour is; 5/18
<h3>Probability of outcome</h3>
The probability that the marbles are the same colour includes:
- The probability of 2 reds, 2 whites, 2 greens.
The total number of marbles = 9 marbles.
Since, the selection is without replacement;
The probability of selecting same colour marbles is;
- {4/9×3/8} + {2/9×1/8} + {3/9×2/8}
The probability of selecting same colour marbles is therefore;

Answer:
<h2>The lengths of the bases of the trapezoid:</h2><h2>
42/h cm and 84/h cm.</h2>
Step-by-step explanation:
The formula of an area of a triangle:
<em>b</em><em> </em>- base
<em>h</em> - height
We have <em>b = 21cm, h = 6cm</em>.
Substitute:
The formula of an area of a trapezoid:
<em>b₁, b₂</em> - bases
<em>h</em><em> - </em>height
We have <em>b₁ = 2b₂</em>, therefore <em>b₁ + b₂ = 2b₂ + b₂ = 3b₂</em>.
The area of a triangle and the area of a trapezoid are the same.
Therefore
<em>multiply both sides by 2</em>
<em>divide both sides by 3</em>
<em>divide both sides by h</em>
Answer:
3/8
Step-by-step explanation:
So, three outcomes give two heads and a tail (HHT, HTH, THH). Therefore, the probability of getting two heads and a tail is 3/8.
Answer:
$450000*0.015=$6750
Step-by-step explanation:
1.5% as a decimal is 0.015
You then multiply the sale amount by the decimal to get $6750
