There are 8! Eight sides on the shape, and all sides are the same shape.
Using the binomial distribution, it is found that there is a 0.125 = 12.5% probability of observing exactly 3 tails.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, considering 3 tosses of a fair coin, the parameters are n = 3 and p = 0.5.
The probability of 3 tails is P(X = 3), hence:


0.125 = 12.5% probability of observing exactly 3 tails.

Answer:
i belive its A $15
Step-by-step explanation:
if $3 is 20% and we are trying to find the full 100% then you miltiply 3 by 5 since 20 times 5 equals 100 and when you multiply 3 by 5 you get 15 dollars which is 100 percent of the iteam meaning the regular price.
