Step-by-step explanation:
As,
![{64}^{ \frac{2}{3} } = {(\sqrt[3]{64})}^{2} = \sqrt[3]{ {64}^{2} }](https://tex.z-dn.net/?f=%20%7B64%7D%5E%7B%20%5Cfrac%7B2%7D%7B3%7D%20%7D%20%20%3D%20%20%7B%28%5Csqrt%5B3%5D%7B64%7D%29%7D%5E%7B2%7D%20%20%3D%20%20%5Csqrt%5B3%5D%7B%20%7B64%7D%5E%7B2%7D%20%7D%20%20)
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%

A. 49°, 59°, 72°
Because this is the only one that equals 180° which is the sum of a triangle
