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
