for one file:
For X = 1,
P(~A and B)
or
P(A and ~B) =
0.6 * 0.3 + 0.4*0.7 = 0.46
Oh, I think I see, the universe for P(A and B) is first
or
second file
while P(~A and B) or P(A and ~B) the universe is first, second or no
file.

Answer:
69 times
Step-by-step explanation:
$225 - $221.75 = $3.25
$221.75 - $218.50 = $3.25
... etc
Therefore pattern is 3.25
Need to find how many times $3.25 can be taken from $225
So
$225/$3.25 = 69.2 times
69 times (whole number)
