i. A probability is usually expressed as a decimal, such as 0.70 or 0.27, but it may be given as a fraction, such as 7/10 or 27/100. ii. The closer a probability is to 0, the more likely that an event will not happen. iii. The closer the probability is to 1.00, the more likely an event will happen. Multiple Choice (i), (ii) and (iii) are all false statements. (i) is a correct statement but not (ii) or (iii). (i) and (iii) are correct statements but not (ii). (i), (ii) and (iii) are all correct statements. (ii) and (iii) are correct statements but not (i).

Which of the following statements are true? Probability is a measure of the likelihood that something will occur. Two events A and B are independent if P(A) = P(A|B). A probability is a number between 0 and 1, where 1 indicates certainty and 0 means impossible. A statistical probability must be very close to its corresponding theoretical probability. Two events A and B are mutually exclusive if P(A) + P(B) = 1.
