I dont knwo what you mean by giant one but 15.75 divided by 0.25 is 63
Answer:
Not independent
Step-by-step explanation:
This problem involves independence criteria for conditional probabilities.
The two events will be independent if P(A/B)=P(A) or P(B/A)=P(B)
Let us assumes that event A is for student attending private college and B is for student graduating in four years.
So we are given the following probabilities
P(A)=0.20
P(B)=0.55
P(B/A)=0.79
As we can see that P(B/A)≠P(B) so the events A and B are not independent.
So based on the above results we can say that "attending a private college or university" is not independent of "graduating in four years". Thus the two events "attending a private college or university" and "graduating in four years" are dependent.
The first one is D. (2+11)7=7(2+11)
I'm not sure of the second one, I apologize.
Yes, sum means the answer to an addition problem. So the sum of 22 and 9 means 22+9. 22+9=31. I hope this helps :)
