Answer:
12 trades
Step-by-step explanation:
Let's call 'x' the number of trades they will do.
After each trade, the number of cards Ian has increase by 1 (he gives 1 but receives 2), and the number of cards Jason has decrease by 1 (he receives 1 but gives 2), so after x trades, the number of cards Ian has is 20 + x, and Jason has 44 - x.
To find the number of trades when they will have the same amount of cards, we have that:
20 + x = 44 - x
2x = 24
x = 12 trades
13 is the answer ...

Answer:
204/100 = 51/25= 2 1/25 that is the answer
So for the dice to be 9 two die must be rolled. So we start with a 1/2 chance.
Then there are 36 possibilities to be rolled on a die (6*6) and there are 4/36 possibilities for the dice to roll a 9 (4+5, 5+4, 3+6, 6+3).
So we multiply 1/2 by 1/9 (4/36)- which equals 1/18.
So there is a 1/18 chance for the result of the dice rolled to be a 9.
I hope this helps!
