Hey guys I need some help with this problem-
What is the probability of these events when we randomly select a permutation of {1,2,3,4}?
c)4 precedes 1 and 4 precedes 2
d)4 precedes 1, 4 precedes 2, 4 precedes 3
e)4 precedes 3 and 2 precedes 1
I got (a) and (b) which were (a)1 precedes 4 =12/24 (b) is the same as (a) since it is just in reverse. But I don't understand how to get the others. Thanks for any help.
