Answer:
Step-by-step explanation:
We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).
p = 12/100 = 0.12
number of success, x = 20
n = 200
the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)
From the binomial probability calculator,
P(x ≥ 20) = 0.84
Hi! your answer should be 7.64 if I am not mistaken
Answer:
30 cm^2 approximately
Step-by-step explanation:
The formula for calculating the area of a octagon is 2 (1 + √2) x^2 (x : side length)
2 + 2√2 × 100 = 30 cm^2 approximately
