No - you can not add them that way. A simple example. The odds of a coin flip being heads are 50/50 So if you add them you get say 50% + 50% on two flips. Of course you know that the odds are not 100% of a head turning up in two flips. The correct figure is 50% + 50% -(50% * 50%). You must subtract the fact that they both may be heads (or tails). In my simple example (I sure hope this is correct) you get .5 + .5 - .25 or 75%. In this case each flip is independant of the others. In your case if you get the card you need on the first try it is irrelevant (for your purposes) but not for mathematics. You have to discount the fact they both could be the card you need. 4/47 + 4/46 - (4/47 * 3/46) It has been a long time and I am not sure this is correct but you have to discount the fact that both could be the card you need. In this case that is about 1/2 % difference. Your way if you kept adding 4/47 + 4/46 + 4/45 + 4/44 you would end up with a % over 100% before its time was due. I am glad there is not a third card cause it gets more complicated. M
