(i) What is the probability that it is a 3?
(ii) What is the probability that it is greater than 5?
(iii) What is the probability that it is an even number?
(i) | (ii) | (iii) | |
A | ^{1}⁄_{7} | ^{3}⁄_{7} | ^{4}⁄_{7} |
B | ^{1}⁄_{7} | ^{4}⁄_{7} | ^{3}⁄_{7} |
C | ^{1}⁄_{7} | ^{2}⁄_{7} | ^{5}⁄_{7} |
D | ^{1}⁄_{7} | ^{5}⁄_{7} | ^{2}⁄_{7} |
