Given two events, D and E, such that P(D)= .340 , P(E) = .450 and P(D intersect E) = .637, then the two events are? a. independent and mutually exclusive

b. independent but not mutually exclusive

c. mutually exclusive but not independent

d. neither independent nor mutually exclusive

e. there is not enough information to answer

First you would have to put the data in order.
119, 121, 146, 220, 241, 280, 297, 353, 387, 393, 436, 455, 460
To find the mean, you add up all the numbers and then divide by how many there are.
3908/13=300.6 (this is rounded to the nearest tenth)
To find the median, you have to look at the middle number
The median here is 297
To find the first quartile, you have to half the data set through the middle and find the middle number on the left
The first quartile is 220
Do the same thing for the third quartile, but look at the right data set
The third quartile is 393

Hope this helps!
