Answer:
c) Either A or B or both occur.
Step-by-step explanation:
Suppose that we have two events
Event A
Event B
We have that:
In which a a happens and b does not and 
is the probability that aboth events happen
By the same logic, we have that:
The union of events A and B is:
Which includes either one of them or both.
So the correct answer is:
c) Either A or B or both occur.
Answer:
9<sqrt(97)<10
Step-by-step explanation:
Perfect squares:
1
4
9
16
25
36
49
64
81
100
121
144
169
....so on
97 is between 81 and 100
So square root of 97 is between sqrt(81)=9 and sqrt(100)=10.
9<sqrt(97)<10
(0+4) = 1(5-0)
