a 18
- simplify 6/18, which should be 1/3. therefore, a = 3.
Answer:
The probability that two orange marbles are drawn (and only those two), is 1/66, or approximately 1.5%
Step-by-step explanation:
The total number of marbles in the bag is 2 + 4 + 6, which equals 12.
We're told that there are two yellow marbles, so the chance of picking a yellow one on the first try is 2/12, or 1/6.
After that marble is drawn, we now have 11 marbles in the bag, and only 1 of them is yellow, so the chance of drawing a second yellow marble is 1/11
The total probability of drawing two yellow marbles then is:
1/6 × 1/11 = 1/66, or approximately 1.5%
Answer:
I think it's true
Step-by-step explanation:
<h2>Correct option :</h2><h3>
</h3><h2>Steps to derive answer :</h2>
Selling price of a bicycle = 2850
Profit percentage = 14%
We know that :
Then, the cost price of this bicycle :
Thus, the cost price of this bicycle = 2500
In another scenario :
Profit percentage = 8%
Cost price of the bicycle = 2500
Then, Selling price will be equal to :
Let x be the selling price of the bicycle.
Therefore, the selling price with a profit of 8% will be = 2700
