Question: Is there a way to move a football picture on a smartboard during a powerpoint slideshow?

I'm trying to create a math football game and I would like to be able to move the football on the smartboard screen while the slideshow is running. Is that possible? If so, how?

Answer: Yes of course it's possible, you should check this website out for step by step instructions http://tinyurl.com/4ytxqgz

Question: Does anyone here know Discrete Math? If yes i need help on a problem!!!!?

Here is the problem:
the purpose of the card game black jack, is to get a count of 21, or as close to it as possible without going over. the value of the cards are as follows:
- aces are woth 1 or 11
- tens, jacks, queens, kings are worth 10
- all other cards are with their number values
"black jack" means taht you get a value of 21 with only 2 cards
ex: king of spades, ace of spades
assume the following questions that you are using a 52 card deck
1. what are the possibilties of getting "21" with 3 cards?
2. what is the probability of getting "21" with 3 cards?
3. in a standard game, the dealer must stay if he/she has 17 or higher; however, must draw another card if he/she has 16 or lower. why? (hint: what are the odds of getting 16, 17)
4. does black jack have better odds for the dealer or the player?

It would be great if someone could answer these? and like explaing how to do each.

Answer: 1.

11-9-1 = 24
11-8-2 = 64
11-7-3 = 64
11-6-4 = 64
11-5-5 = 24
10-10-1 = 480
10-9-2 = 256
10-8-3 = 256
10-7-4 = 256
10-6-5 = 256
9-9-3 = 24
9-8-4 = 64
9-7-5 = 64
9-6-6 = 24
8-8-5 = 24
8-7-6 = 64
7-7-7 = 4

2. The combination of 52 choose 3 is 52!/3!(52-3)! = 50*51*52/6 = 22100. The sum of the results from number one is 2012. Therefore the probability of gettting "21" with three cards is 2012/22100 ≈ 9.1%.

3. My answer would be too speculative.

4. Based on your rules, the dealer and the player have the same odds of hitting blackjack with 2 cards.
