D. Is correct like they said
Answer:
12
Step-by-step explanation:
add the numbers to get the total then divide the total by the amount of columns/numbers.
12 + 12 + 18 + 6 = 48
48 / 4 = 12
Its going to be (8/15) and (12/5)
Answer:
1.5267% probability that he loses AT MOST 3 times
Step-by-step explanation:
For each game that Andy plays, there are only two possible outcomes. Either he wins, or he loses. The probability of winning a game is independent of other games. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
The chance of winning a certain game at a carnival is 2 in 5.
So the chance of losing is (5-2) in 5, that is 3 in 5.
So 
12 games:
This means that
.
What is the probability that he loses AT MOST 3 times?
.
In which:






1.5267% probability that he loses AT MOST 3 times
