Assume the coin is fair, so there are equal amount of probabilities for the choices.
There are two possible choices for a flip of a fair coin - either a head or a tail. The probability of getting a head is ½. Similarly, the probability of getting a tail is ½.
Use Binomial to work out this problem. You should get:
(5 choose 4)(½)4(½).
- (5 choose 4) indicates the total number of ways to obtain 4 tails in 5 flips.
- (½)4 indicates the probability of obtaining 4 tails.
- (½) indicates the probability of obtaining the remaining number of head.
Therefore, the probability is 5/32.

Suppose that you toss a coin and roll and die What is the probability of obtaining tails?
The probability to tossing a coin and obtaining tails is 0.5. Rolling a die has nothing to do with this outcome - it is unrelated.
