<h3>Answer:</h3>
1/2, 2, 7/2, 5
<h3>Step-by-step explanation:</h3>The differences between adjacent terms of an arithmetic sequence are the same.
No sequence in which signs alternate can be an arithmetic sequence. This eliminates the 1st and 4th choices.
The denominators of the 2nd sequence are an arithmetic sequence, meaning that sequence is a "harmonic" sequence, not an arithmetic one. The differences between adjacent terms get smaller and smaller. They are not a constant.
Differences between terms of the 3rd sequence are all 3/2. This is your arithmetic sequence.

a) The possible values of X are as follows
X = {0,1,2,3,4}
P(x) = P(X=x)
b) The cdf in this case, as in the F(x), comes out to be a step function graph on the basis of values obtained from the probability mass function.
c) To find out the probability when more women are interviewed than me, add together the matrices from when value of X is equal to 2, 3 and 4 (from part a).
