Answer:
P(first marble will be green and the second will be green as well)= 5/22
Step-by-step explanation:
A goblet contains 2 red marbles, 6 green marbles, and 4 blue marbles.
Total number of marbles= 2+6+4
=12
P(first marble is green)=no. of green marbles/total number of marbles
= 6/12
= 1/2
P(second marble is green and we didn't put the first marble back)
=no. of green marbles left/total marbles left
= 5/11
Hence, P(first marble will be green and the second will be green as well)
=
= 5/22
This sounds like a very poor business model right from the beginning.
The mine continuously operates at a loss, and it has nothing to sell.
If it uses 14 tons an hour just to keep running, and it produces 2 tons
an hour, then it doesn't take a business genius to point out that this
operation is rapidly digging itself straight into the ground.
I'm guessing that there was a major mistake made during the copying
of the problem.

Answer: x = 32/7
Step-by-step explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x. I hope this is the answer you're looking for.
Answer: No, the events are not mutually exclusive
Work Shown:
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.51 + 0.79 - 0.66
P(A and B) = 0.64
Since the result is not zero, this means the events are not mutually exclusive.
Mutually exclusive events are ones that cannot happen at the same time. Example: getting a "2" and a "3" on the same roll of a number cube.
