A study was done to see what type of fast food students go to most on the weekend and which day they go to that restaurant.  The table below shows the results.

  Friday Saturday Sunday Row Total
Pizza 27 35 18 80
Burger 20 17 30 67
Mexican 15 25 22 62
Other 12 7 15 34
Column Total 74 84 85 243

If this survey represents the general population of students, find the probability that a student selected at random will

A.  Most often go to a Mexican restaurant on Fridays.

B.  Most often go to a Burger place given that that student eats at fast food restaurants most often on Sundays

C.  Most often eats Pizza or eats out on Saturdays.
