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:
~22,000 /yr
Step-by-step explanation:
52 weeks/yr
5 day work week (8 hrs a day 40hrs a week)

n is the number of games. In this case it is 15. Enter this number into the function:
b(n) = 12n = 12(15) = 180.
Simply put, 12 balls are needed for each game.
15 x 12 = 180</span>
Answer:
9
Step-by-step explanation:
The number of darts that failed to hit the bulls eye is 40% of 15 subtracted from 15
Since 40% of the darts hit the bulls eye .
Therefore
40% of 15
40/100 x 15
0.4 x 15
6
This means that 6 darts hit the bulls eye.
Therefore,number of darts that did not hit the bulls eye is
15 - 6 = 9
9 darts failed to hit the bulls eye
