Jackson goes to the gym 1, 2 or 3 days in a week, depending on work demands at the office. The probability that he goes 1 day is 0.1, the probability that he goes 2 days is 0.65, and the probability that he goes 3 days is
0.25. What is the expected value of the number of days per week for which Jackson goes to the gym?

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
