Find the probability of obtaining exactly one head when flipping eight coins. express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

The probability of obtaining exactly one head when flipping eight coins is 0.03125

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

If sample space of flipping "n" coins is expressed as 2^n

If eight coins is flipped, the total outcome will be 2^8 = 256

If exactly one head is obtained, the expected outcome will be 8

Pr(obtaining exactly one head ) = 8/256

Pr(obtaining exactly one head ) = 0.03125

Hence the probability of obtaining exactly one head when flipping eight coins is 0.03125
