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

1/16

Step-by-step 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

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