1 - the chance to draw 2 jacks - the chance to draw no jacks leaves you with the chance to draw just one by elimination.
1 - (1/3)*(1/3) - (2/3)*(2/3)
1 - 1/9 - 4/9
1 - 5/9

The answer depends on the probability distribution function for the random variable.
The probability is 0.

False. It is approximately 1. Theoretically, it is not 1. I used excel, and I know the probability is between 0.999999 and 1. as the probability of Z<6 is 0.999999. I can't calculate the probability exactly because excel only goes to 7 place accuracy.
Assuming that the tiles spell ALGEBRA, the probability is1/7*4/7 = 4/49

You find the event space for the random variable that is the required sum and then calculate the probabilities of each favourable outcome. In the simplest case it is a convolution of the probability distribution functions.
The probability is approximately 4/2500. NOT!

The probability that it contains exactly 3 balls is 6/45 = 0.133... recurring.
Probability is used everywhere: Betting odds. Medical odds, (chance of survival or chance of side effect happening). Anywhere we calculate risks (insurances calculate premiums based on probability). Communication Networks
