How do you construct a probability tree for overlapping events? I'm new to probability so apologies if this question is very basic.
I was preparing a tree for an experiment involving drawing two cards from a deck of 52, one after the other.
The events of interest were the probability of drawing an ace followed by a black card.
The first part of the tree was simple - 4/52 for an ace, 48/52 for a non-ace.
The second part though, got me puzzled. The probability of drawing a black card on the second draw depends on whether the initial card was black. But the way the tree was formulated, the color of the 1st card is not revealed.
What exactly is going on here? Is the tree impossible to complete because it was not properly formulated?
Thanks for any tips / insights!

You need a slightly more sophisticated tree
