Susan works three days a week in a row.

John works three days a week, not necessarily in row.

Their choosing process of days worked are independent of one another.

What is the probability that they will work two of the same days a week, four weeks in a row?

I calculated at first (2/7)*(2/7)=(4/49) that they would work the same two days i one week.

I then applied the probability of consecutive events by multiplying (4/49)*(4/49)*(4/49)*(4/49)=.000044, or .0044% chance...

I am not sure I did this right, or how to account for Susan working three days in a row-

anybody out there that can give me a lending hand?
