Answer: Our required probability is 0.99338.
Step-by-step explanation:
Since we have given that
n = 100
p = 0.200
So, 
So, we can apply normal approximation.
Mean = 20
Standard deviation = 
Since 
So, Probability that fewer than 30 but a packet after testing a free sample is given by

Hence, our required probability is 0.99338.
None of them really, but C is equivalent to the Triognometric Pythagorean Theorem:



That's the Trigonometric Pythagorean Theorem

If they have the same numerator and denominator for example 4/4 and 2/2 are equivalent because you could divide 4/4 to get 2/2 or multiply 2/2 to get 4/4
