Answer:
A (1\(3^4))
Step-by-step explanation:
3^-8\3^-4 = 3^4\3^8 =1\3^4
Hello!
As the ball was replaced, the denominator in our probabilities will be the same. As the each had a 1/6 chance of getting the ball with the certain number, we just square the number as they both had the same probability.
1/6·1/6=1/36
There was a 1/36 chance of them selecting the same ball. This is also equivalent to about a 2.8% chance of this event occurring.
I hope this helps!
75 mi^2
area of a triangle = 1/2 (L • W)
[1/2 (10mi • 5 mi)] • 2 = 50 mi^2
[1/2 (5mi • 5 mi)] • 2 = 25 mi^2
50 mi^2 + 25 mi^2 = 75 mi^2
