What is the Probability that the Lowest Card out of 4 Cards is X? If I have four different value cards, what is the probability that the lowest card (ace, lowest -> king, highest) is some value X?
Here is what I have so far:
I know that the lowest value card cannot be a king, queen, or jack, as there must exist a value that is 3 above. And I can guess that the probability of an ace will be the highest and a 10 will be the lowest. Can someone please give me some hints on how I should approach this?

In this example we are going to calculate the probability of the lowest card being 3.
There are 13x12x11x10=17160 combinations of cards. There is 1 combination to get a 3 on the first card, 10 combinations to get higher than 3 on the next card, 9 combinations on the 3rd, and 8 on the 4th. The total number of combinations is 1x10x9x8. Because this can be started anywhere on the 4 cards, you multiply the result by 4, so the probability of getting any of these combinations is 10x9x8x4/17160=24/143.
We can see that in terms of $x$, which in this example is 3, the formula is $4(13-x)(12-x)(11-x)/17160=8x/143$.
Note: It could be (7+$x$).../17160 but it wouldn't work for other numbers.
