Answer:
1 5/6
Step-by-step explanation:
first convert to /12 and put the wholes in the fraction:
6 3/4 = 81/12
4 11/12 = 59/12
Then perform the subtraction
81/12 - 59/12 = 22/12
... and simplify
22/12 = 11/6
separate the wholes
11/6 = 6/6 + 5/6 = 1 5/6
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
