An exam was given to a group of freshman and sophomore students. The results are below:
Freshman: 106 got A’s, 130 got B’s, and 149 got C’s.
Sophomore: 192 got A’s, 118 got B’s, and 168 got C’s.
If one student is chosen at random from those who took the exam, find the probability that:
b)The student was a freshman or received a C .
c) The student was a sophomore, given they got a
C.
d) The student got an A, given they are a freshman.
