Answer:
The probability of getting all heads in a single coin toss is 1/2, since there are two equally likely outcomes (heads or tails).
Assuming that the coin tosses are independent (i.e., the outcome of one toss does not affect the outcome of any other toss), the probability of getting all heads in 5 tosses is the product of the probabilities of getting a head on each individual toss:
P(all heads) = (1/2)^5 = 1/32
Therefore, the probability of getting all heads in 5 tosses of a coin is 1/32, or approximately 0.03125, in binomial probability.
