A coin is flipped 8 times. Find the probability of the event: exactly 8 heads a. 0.004
b. 1
c. 0.0625
d. 0.129

a) 0.004

The probability of getting exactly 8 heads

P(X=8) = 0.004

Step-by-step explanation:

Explanation:-

The probability of getting a Head, p =

 The probability of getting a Tail, q =

A coin is flipped 8 times

 n = 8

Let 'X' be the random variable in a binomial distribution

The probability of getting exactly 8 heads

Final -

The probability of getting exactly 8 heads

P(X=8) =0.0039≅ 0.004

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
