Answer:
0.173 probability that she gets exactly three questions correct.
Step-by-step explanation:
For each question, there are only two possible outcomes. Either she guesses the correct answer, or she does not. The probability of guessing the correct answer for a question is independent of other questions. 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.
Seven questions:
This means that
Each question has four choices.
Abby guesses, which means that
Find the probability to the nearest thousandth, that Abby gets exactly three questions correct.
This is P(X = 3).

Rewrite the equation with parts separated:
8 + 7/9 - 3 - 2/3
Solve the whole number parts:
8 - 3 = 5
Solve the fraction parts:
7/9 - 2/3
Find LCD of 7/9 & 2/3
7/9 - 6/9 = 1/9
5 + 1/9 = 5 1/9
