Answer:

Step-by-step explanation:
![\sqrt{8} = \sqrt{4*2} = \sqrt{4} * \sqrt{2} = 2*\sqrt{2} = 2\sqrt{2} \\\\\sqrt[3]{8} = \sqrt{2*2*2} = 2](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D%20%3D%20%5Csqrt%7B4%2A2%7D%20%3D%20%5Csqrt%7B4%7D%20%2A%20%5Csqrt%7B2%7D%20%3D%202%2A%5Csqrt%7B2%7D%20%20%3D%202%5Csqrt%7B2%7D%20%5C%5C%5C%5C%5Csqrt%5B3%5D%7B8%7D%20%3D%20%5Csqrt%7B2%2A2%2A2%7D%20%20%3D%202)

Answer:
0.2752512
Step-by-step explanation:
The formula you are looking for is the binomial probability:
n!
P (X) = ------------ * (P)^X * (q)^n - X
(n- X)! X!
For your particular problem:
n=7
X=2
q = 1-p = .8
7!/(5!*2!)*(.2)^2*(.8)^5 = 0.2752512
Hope this helps, have a nice day/night! :D
