Answer:
1.2}3,2
Step-by-step explanation:
4: 7,14,21,28,35
6: 10,8,6,4,2
8: 9,7,5,3,1
You have to add and divide for the mean(average) so add all of them up and then divide by 3 :)
Answer:The probability of the complement of an event is one minus the probability of the event. Since the sum of probabilities of all possible events equals 1, the probability that event A will not occur is equal to 1 minus the probability that event A will occur.
Step-by-step explanation:Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.
Answer:
The mean number of the students who develop hypertension over a life time is 7.8.
Step-by-step explanation:
For each person, there are only two possible outcomes, either they will develop hypertension, or they will not. The probability of a person developing hypertension is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
Suppose that the probability that a person will develop hypertension over a life time is 60%.
This means that 
13 graduating students from the same college are selected at random.
This means that 
Find the mean number of the students who develop hypertension over a life time

The mean number of the students who develop hypertension over a life time is 7.8.
