Answer:
The value of n is 7.
Step-by-step explanation:
For each teen, there are only two possible outcomes. Either they buy soda at least once each week, or they do not. Since they were selected randomly, the teens are independent of each other, which means that 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.
In the binomial distribution, we have that n is the size of the sample. In this question, seven teens are randomly selected, which means that the value of n is 7.

3/100 = 0.03
0.03x400 = 12

Step-by-step explanation:
As a coach for the local soccer team, you want your team to score a goal in the next big game. You look back on last year's stats to make a prediction, with the data shown below the complete table will be
<h3>What is the probability of scoring goals?</h3>
Generally, the equation for the probabilities is mathematically given as


For 1 goal
P(1)= 4/12
For 2 goal
P(2)= 2/12
For 3 goal
P(3)= 2/12
For 4 goal
P(4)= 2/12
