Draw a tree diagram illustrating the events, two cards are drawn in succession with replacement from a standard deck of 52 and its suit is observed. How many total branches exist in this tree diagram?

The tree diagram shows the possible ways or outcomes of the experiments. In the first draw, there are 52 possible outcomes while for the second draw, considering there is no replacement, there are 51 ways. Multiplying these numbers, the answer would be 2652.
