Flip a coin 100 times. we want the chance of getting exactly 50 heads. what is the exact probability, correct to six decimal places? what is the normal approximation of the probability, to six decimal places?

a) 0.079589 b) 0.079656

Step-by-step explanation:

Since we have given that

Number of times a coin is flipped = 100 times

Number of times he get exactly head = 50

Probability of getting head =

We will use "Binomial distribution":

Probability would be

Using "Normal approximation":

n = 100

p = 0.5

So, mean =

Standard deviation is given by

So,

Hence, a) 0.079589 b) 0.079656

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
