we have the numbers 1-10 on each of 4 suits of cards, the others are Jack,Kind and Queen. So there are fours 2s, fours 4s four 6s four 8s and four 10s which is 4x5 or 20 even cards.. There are also 20 odd ones, so 40 even and odd then add 4x3=12 J,K, Q and you have 52 cards
There are 50 8s in 400
There are 70 8s in 560

I assume we do not replace the 8's after we pick one of them. This is sampling without replacement. Since there are four 8s, the odd of picking one of them out of 52 cards is 4/52 the first time, then we have three 8s left and only 51 cards so, 3/51 and then 2/50 the third time. The odd of drawing three consecutive eights is the product of those three probabilities. This is 4/52x3/51x2/50
