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:
21
Step-by-step explanation:
To solve the problem you can just leave the negatives behind for a while.
You then divide 294 by 14 using the normal method of division you prefere.
The answer you get is 21.
So now when the signs of the numbers are the same (negative or positive) The answer after dividing is always a positive number thus the answer remain 21.
