Answer:
85.56% probability that less than 6 of them have a high school diploma
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have a high school diploma, or they do not. The probability of an adult having a high school diploma is independent of other adults. 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.
50% of adult workers have a high school diploma.
This means that 
If a random sample of 8 adult workers is selected, what is the probability that less than 6 of them have a high school diploma
This is P(X < 6) when n = 8.
In which
85.56% probability that less than 6 of them have a high school diploma
Answer:$58.50
Step-by-step explanation:
The price was 130
With 40% off
Which reads out in this format
40/100*130= 52 dollars off the real price
130-52=78 dollars
Then later reduce by 25 percent
Now the price is 78 dollars
25/100*78= 19.5 dollar off the new price
So the real price will be
78-19.5=$58.5
This is a problem in binominal probability. Either the rented film is a comedy or is not a comedy (binary outcomes). the probability that the rented film is a comedy is 52%.
You must calculate and add together three probabilities to derive a final answer:
binompdf(7,0.52,0), binompdf(7,0.52,1) and binompdf(7,0.52,2).
Can you do this? Let me know if you need further help with this problem.
