Twelve percent of the population is left handed. Approximate the probability that there are at least 20 left-handers in a school

DochEvi [55]

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:

B. 15

Step-by-step explanation:

The chances of randomly selecting keys for a sports car or convertible is 5/40 since there are a total of 5 sports and convertible car keys and a total of 40 keys overall. We then multiply that 5/40 by 120 because Sam randomly selects a key 120 times.
