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

if he has no friends he cant give them out to his friends

step-by-step explanation:

no friends = cant give anything out

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
