_________________________________________________
If a student is selected at random, find the probability
a) the student has taken exactly two tests = 2/30
b) the student has taken at least two tests 10/30
c) the student has taken at most three tests = 25/30
d) the student has taken 3 or fewer tests= 25/30
e) the student has taken one or two tests.= 20/30
