Question

A coin is flipped 8 times determine the probability that a least 1 heads appear face up​

Answer 1

1/8 chance

Explanation:

if you flipped it 8 times then you will have a 1 in 8 chance

Answer 2

the probability is 99.6%

Explanation:

The probability of having at least one head is:

`P(x)=1-P(NoHead)`

The probability of having no heads is given by:

`P(NoHead)=P(tail)^(n)=((1)/(2))^8=(1)/(256)`

so:

`P(x)=1-(1)/(256)=(255)/(256)=99.6\%`
