To find the probability of getting exactly 6 tails when a coin is tossed 12 times, you can use the binomial probability formula, which is:
Where:
- is the number of trials (in this case, 12 tosses).
- is the number of successes (in this case, 6 tails).
- is the probability of success on each trial (for a fair coin, ).
- represents the number of combinations of items taken at a time.
Substitute the values into the formula:
Calculate:
So, the probability of getting exactly 6 tails when a coin is tossed 12 times is approximately 0.2256.

To find the probability of getting exactly 6 tails when a coin is tossed 12 times, you can use the binomial probability formula.
The binomial probability formula is:
Where:
- is the total number of trials (in this case, the number of coin tosses)
- is the number of successes (in this case, the number of tails)
- is the probability of success on each trial (for a fair coin, )
- is the number of combinations of items taken at a time (this represents the number of ways to get exactly tails in tosses)
Substituting the given values into the formula:
Now, calculate :
Now, substitute this value into the equation:
So, the probability of getting exactly 6 tails when a coin is tossed 12 times is approximately 0.2256, or about 22.56%.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
