Given:
Number of red marbles = 5
Number of blue marbles = 4
Number of yellow marbles = 3
To find:
The probability of pulling a red marble, then pulling a blue marble, without replacement.
Solution:
Probability formula:
We have,
Number of red marbles = 5
Total number of marbles is:
Probability of getting a red marble is:
After selecting one red marble, the remaining number of marbles is 11 and the number of blue marbles is 3. So,
Now, the probability of pulling a red marble, then pulling a blue marble, without replacement is:
Therefore, the correct option is B.
Answer:
A = 75°
B = 90°
C = 15°
Step-by-step explanation:
The diagram tells us that C = 15°.
The diagram places a square in the angle of B, showing you the angle is a 90° right angle.
You can solve for A because all angles of a triangle must equal 180°. 180° - 90° (B) = 90°. 90° - 15° (C) = 75°, the measure of A.
The company needs to sell at least 580 cameras to cover the expenses, if they increased there sales by 50 cameras per day they would make a $250 profit.
<span>To add 1/10 and 8/100, they must have the same denominator.
To do this, multiply 1/10 by 10/10 (which equals one, so it doesn't change the value of the fraction).
Now you have 10/100 and 8/100. To add them, simply add the numerators and keep the denominators the same.
This results in 18/100, which can be simplified to 9/50.</span>
