i. The probability of an event, based on a classical approach, is defined as the number of favourable outcomes divided by the total number of possible outcomes. ii. If among several events only one can occur at a time, we refer to these events as being mutually exclusive events.
iii. The probability of rolling a 3 or 2 on a single die is an example of conditional probability.
A) (i), (ii) and (iii) are all correct statements
B) (i) and, (ii) are correct statements but not (iii).
C) (i) and, (iii) are correct statements but not (ii).
D) (ii) and, (iii) are correct statements but not (i).
E) (i), (ii) and (iii) are all false statements.

Statement (i) is correct and is a fundamental concept in classical probability. Statement (ii) is also correct and applies to situations where events cannot occur simultaneously. However, statement (iii) is incorrect as the probability of rolling a 3 or 2 on a single die is an example of simple probability, not conditional probability. Conditional probability involves the probability of an event happening given that another event has already occurred.
