Probability that you have chosen 2 red marbles is 3/11
<h2>How to solve?</h2>
Total number of marbles = 6 + 5 = 11
Number of red marbles = 6
Number of blue marbles = 5
Important Points:
1. Replacement is not allowed
2. Blue is followed by Red
Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.
Probability of Blue first = 5/11
Probability of Red second = 6/10 (one marble is already taken out)
Probability = 5/11 * 6/10 = 3/11

Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
To find the quotient, divide 396 by 12.
396/12= 33
FIRST PROBLEM AS GENIUS!!!
The 45-45-90 triangle theorem states that each leg equals x, and the hypotenuse equals
. Using this, we can find that the height is 10. Take the average of the lengths to get l = 27.
The area = 270.
I dont see anything maybe you forgot to add the answer'
