Solution When two dice are thrown , total possible outccomes=36 Favorable outcomes for 4 will not come up either time: { (1,1) (1,2) (1,3) (1,5) (1,6)} { (2,1) (2,2) (2,3) (2,5) (2,6)} { (3,1) (3,2) (3,3) (3,5) (3,6)} { (5,1) (5,2) (5,3) (5,5) (5,6)} { (6,1) (6,2) (6,3) (6,5) (6,6)} Number of favorable outcomes = 25 p (4 will not come up) = 25/36

Explanation: When you flip a coin there are two possible outcomes (heads or tails) and when you roll a die there are six outcomes (1 to 6). Putting these together means you have a total of 2 ×6 = 12 outcomes. P (H,3) = P (H) × P (3) = 1 2 × 1 6 The chances of flipping a head and rolling a 3 is 1 12 Answer link

. There are 3 positions to be filled. ____+ ____ +____ = 15 The possible combinations are Case 1: (6 6 3) (6 3 6) (3 6 6) total 3 combinations Case 2: (4 5 6) (4 6 5) (5 6 4) (5 4 6) (6 5 4) (6 4 5) total 6 combinations Case 3: (5 5 5) only 1 combination So probability is possible/total

May 4, 2016 It is not indicated whether the first card is replaced before the second is taken. Let's consider both cases. P rob = number of desirable outcomes total number of possible outcomes There are 4 aces in a deck of cards which has 52 cards in total. If the first card is NOT replaced: P (Ace, Ace) = 4 52 × 3 51 = 1 221
