Answer:
0.25
Step-by-step explanation:
72% of courses have final exams and 46% of courses require research papers which means probability of 0.72 for courses that have final exams and 0.46 for courses that require research papers.
31% of courses have a research paper and a final exam, which means probability of 0.31 for both courses with exams and research papers, using Venn diagram approach, find picture attached to the solution.
P(R or E) = P(R) + P(E) - P(R and E), which gives:
P(R or E) = 0.15 + 0.41 - 0.31
P(R or E) = 0.25.

Answer:
7 1/6
Step-by-step explanation:
So first step, you subtract the two regular numbers like any other subtraction. 15-7 is 8. Now u have 8 - 5/6, so you change 8 into 7 6/6 - 5/6, since 6/6 is still 1. Now since you have a common denominator, you just subtract the fractions and get 7 1/6.
64in/16in = x/18.5
64•18.5= 1184
1184/16x= 16x/16x
1184/16x
x= 74 in
