Find the probability of getting at least one tail when tossing 4 fair coins. Round to three decimal

pr(one tail)=1-pr(all heads)=1-(1/2)^4

To find the probability of getting at least one tail when tossing 4 fair coins, we need to find the probability of the complement event, which is getting all heads, and then subtract it from 1.

The probability of getting a head on one toss of a fair coin is 1/2, and since each coin toss is independent, we can multiply these probabilities together.

So, the probability of getting all heads when tossing 4 fair coins is (1/2) * (1/2) * (1/2) * (1/2) = 1/16.

Now, to find the probability of getting at least one tail, we subtract the probability of getting all heads from 1:

1 - 1/16 = 15/16.

So, the probability of getting at least one tail when tossing 4 fair coins is 15/16, which is approximately 0.938 when rounded to three decimal places.
