C = 2 x pi x r
divide each side by 2 x pie to get r by itself.
45/(2(3.14)) = r
r = 7.17
Answer:
0.2833 = 28.33% probability that a student in the class chosen at random is neither an Actuarial Statistics nor a Data Science major
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 300 students.
80 + 5 = 85 are not Actuarial statistics or data science majors. So

0.2833 = 28.33% probability that a student in the class chosen at random is neither an Actuarial Statistics nor a Data Science major
Five fractions that are near to the fraction two-thirds but not equivalent or 1/2 1/4 3/6 5/9 15/21.
Hope this helps!!!!
