Does that say hundred thousands if so the value is 6
6.6766*10^4 is that number in scientific notation
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
Answer:2349.91
Step-by-step explanation:
A=2πrh+2πr2=2·π·11·23+2·π·112≈2349.9113
