Question

A coin is tossed 5 times what is the probability that there is at least one head on the top ? 1 point

Answer 1

Hey!!!

Here is your answer____________


The probability that no heads occurs is


P(no heads) = P(all tales) =

P(tales) * P(tales) * P(tales) * P(tales) * P(tales)

= 1/2 * 1/2 * 1/2 * 1/2 * 1/2

= 1/32.



To get the answer to your question


P(no heads) + P(at least one head) = 1


1/32 + P(at least one head) = 1


ie. P(at least one head) = 1 - 1/32


= 31/32


Hence, the probability that at least one head is on top is 31/32.
