Question

Four coins are flipped. What is the probability of the coins all landing heads up ?

Answer 1

1/2 1/2 1/2 1/2. Is the answer

Answer 2

1/16

Explanation:

The Probability of getting heads out of the two options (head or tails)

P(h) = 1/2 = heads / total

Each coin flip is an independent event so we can multiply the probabilities

4 heads in a row = P(h)*P(h)*P(h)*P(h)

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

1/16
