question 50

Multiple Choice

i. The complement rule states that the probability of an event not occurring is equal to one minus the probability of its occurrence. ii. If there are two independent events A and B, the probability that A and x B will occur is found by multiplying the two probabilities. Thus for two events A and B, the special rule of multiplication shown symbolically is: P(A and B) = P(A) P(B) .
iii. The general rule of multiplication is used to find the joint probability that two events will occur. Symbolically, the joint probability P(A and B) is found by: P(A and B) = P(A) P(B/A) .

• B) (i) and, (ii) are correct statements but not (iii).
• C) (i) and, (iii) are correct statements but not (ii).
