Answer:
The probability of observing between 43 and 64 successes=0.93132
Step-by-step explanation:
We are given that
n=100
p=0.50
We have to find the probability of observing between 43 and 64 successes.
Let X be the random variable which represent the success of population.
It follows binomial distribution .
Therefore,
Mean,
Standard deviation , 
![\sigma=\sqrt{100\times 0.50(1-0.50)]](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7B100%5Ctimes%200.50%281-0.50%29%5D)

Now,






Hence, the probability of observing between 43 and 64 successes=0.93132
Yes they are because if I made a small statement like oh I like your shirt it's still called a statement.
Answer:
5p - 50
You distribute
5 x p
5 x -10
It would be (B) because 450+200x4=2620 fence posts
