ANSWERS
1. Find P(3 or 5) on a number cube. 1/6 + 1/6 = 2/6 = 1/3
2. Susie rolls a regular number cube - is it likely, unlikely, or neither likely nor unlikely that she rolls an even number? neither
likely nor unlikely since the probability of rolling an even number is 3/6 = 1/2
3. Bob draws a card from a deck, keeps the card, and then draws another - is it likely, unlikely, or neither likely nor unlikely that
he draws a spade and a 7? the probability of drawing a spade is 13/52 and the probability of drawing a seven is 4/51 (he
kept the card after the first draw). Multiplying the fractions, we end up with a probability of 52/2652 (or 1/52 if
simplified), which is an unlikely result
