Step-by-step explanation:
- Number of red = 2
- Number of blue = 5
- Number of green = 3
- total number of marbles = 10
<h3>
probability of not choosing a red marble = 1--choosing a red marble.</h3>
<u>Because</u><u> </u><u>probability</u><u> </u><u>is</u><u> </u><u>always</u><u> </u><u>one</u><u>(</u><u>1</u><u>)</u><u>.</u>

Answer:
m = 4
Step-by-step explanation:
Given
- 8 + 6m = 
(4m + 16) ← distribute parenthesis
- 8 + 6m = 2m + 8 ( subtract 2m from both sides )
- 8 + 4m = 8 ( add 8 to both sides )
4m = 16 ( divide both sides by 4 )
m = 4
I got 45 for this, not sure if it’s right. Hope that helps. :D
Given parameters:
Cost price of the article = Nu.28.30
Selling price of the article = Nu.29.30
Unknown:
Gain percentage = ?
The gain percentage is the same as the percentage profit on a trade.
The formula is given as:
Gain percentage = 
Profit = Selling price - Cost price
= Nu.29.30 - Nu.28.30
= Nu. 1
Now input the parameters and solve;
Gain percentage = 
= 3.5%
The gain percent is 3.5%
