The solution to your problem about the probability <span>of getting first a red and then a black marble is as follows:
</span><span>(3 red / 8 total) * (2 black / 7 total) = 3/28
</span>
Therefore, the probability of getting first a red and then a black marble is 3/28.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
4.70, all the others can be simplified to 4.07 by taking away the zeroes after the 7 because they are not significant, The one before the 7 stays because it is significant as it is holding the tenths place value.
48/8 can equal 6. I hope this helps!
A=(a+b)*h*1/2=(20+8)*7*1/2=49 m2
V=A*H=49*2=98 m3
Problem:
The area of the patio of a relative's house is 20 square meters.
The width of the patio is 2 meters.
What is the length of the patio?
Solution:
The area is:
A = (w) * (l)
Where,
w: width
l: long
Clearing l we have:
l = A / w
Substituting values:
l = 20/2
l = 10 meters
