Question

There are two spinners, one numbered 1-6 and one labeled A & B. Spin them only once. Draw a tree diagram showing the probability of spinning 1,A

Answer 1

We cannot show a tree diagram via this medium. However, it would be easier to start your tree with A and B.

Chances of 1 = 1/6
Chances of A = 1/2

To find the probability of both (or all) probabilities occurring, multiply the individual probabilities.
