Construct a tree diagram to represent this situation.

In California, Texas, and New York, $40$percent, $25$ percent, and $35$ percent of computers are built, accordingly. Laptops created in California, Texas, and New York account for $75$ percent, $70$ percent, and $50$ percent of the total.

The universal multiplication rule $P(AB)=P\left(A\right)\times P(B|A)$can be used to get the probability that events A and B both occur, where $P(B|A)$is the conditional probability that event $B$occurs provided that event$A$has already occurred. There's another technique to simulate random behaviour that incorporates a sequence of outcomes, such as tossing coins, where the outcome of one toss is independent of the outcome of any other throw. A tree diagram is what it's called.

A tree diagram might be created using the information provided as follows:
