Question

whats the probability of getting 1 or 3 fives on 10 rolls of a fair dice? Hint: Remember the rule for finding P(AorB)
A. N(10,1/6,1) + N (10,1/6, 3)
B. B(10,1/6,3) + B (10,1/6,5)
C. N (10,1/6,1) X N(10,1/6,3)
D. B (10,1/6,1) X B (10,1/6,3)
E. B (10,1/6,1) + B (10,1/6,3)
I think its E because the hint is P(AorB) and A would be 1 and B would be 3 in this case...i believe?
