Hi 
This is a better look: 
Class      | Yes    | No      | No Op     Total

Freshman   | 15     | 8       | 6           29
Sophomores | 25     | 3       | 2           30
Total        40       11        8           59


a. The student who has no opinion = 8/59  Good Work
b. The student who is a freshman = 29/59 0r is against the issue = 11/59
Need to Know: P(A 0r B) = P(A) + P(B) - P(A and B)
P(F or NO)   = 29/59 + 11/59  {{{- 8/59}}} = 32/59
c. The student is a sophomore = 30/59 or favors the issue = 40/59.
 P(S 0r YES)   = 30/59 + 40/59  -  25/59 = 45/59
