According to the calculation, each visitor went down, on average, 11.41 times.
<h3><u>Averages</u></h3>
Given that a water park keeps track of the number of times each visitor goes down water slides during their visit, and 12 visitors went down a water slide 4, 22, 16, 10, 11, 20, 20, 12, 6, 3, 11 and 1 times, to determine the average number of times each visitor went down, the following calculation must be performed:
- (4 + 22 + 16 + 10 + 11 + 20 + 20 + 12 + 6 + 3 + 11 + 1) / 12 = X
- 137 / 12 = X
- 11.41 = X
Therefore, each visitor went down, on average, 11.41 times.

Answer: 0.9738
Step-by-step explanation:
This is solved by the probability distribution formula for random variables where probability of determining random variable X is given by
P(X=r) = nCr * p^r * q^n-r
Where n = number of sample = 6
p = probability of success = 0.545
q = 1-p = 0.455
r = possible outcome from number of sample.
If 6 random births are chosen, Probability that at least 1 of them is a girl = 1 -[probability that none of them is a girl] = 1 - [probability that all 6 kids are boys]
Probability that all 6 kids are boys = 6C6 * 0.545^6 * 0.455^0 = 0.0262
Probability that at least one is a girl = 1 - 0.0262 = 0.9738.
F=1
Add 22 to both sides, then divide both sides by 3
10.4% as a fraction is 104/1000
