Multiply the probability of hitting the first spin by the probability of hitting the second spin. Dice: 3/6 or 1/2 There are 3 numbers out of 6 that will give Joann the win. Cards: 4/52 times 3/51 = 12/2652 = 1/221 The odds of drawing an ace out of a full 52 card deck are 4/52 or 1/13. If you draw an ace and keep it, then there are now 3 aces in a 51 card deck, so the probabilty of drawing the second ace is 3/51 or 1/17. Multiply to get the probability of drawing two aces.

The probability twice in a row is 1/64^^2, or 1/4096. 2)Six possible rolls. Three winning rolls. Think a little harder. This one is really too easy to need help on. 3) Probability of an ace the first time is 1/13. That leaves a deck with 51 cards and 3 aces, so the probability of drawing another is 1/17. So two in a row is 1/221. 1) The probability of winning the jackpot is 1/64. The probability twice in a row is 1/64^^2, or 1/4096.
