How many leaves on a tree diagram are needed to represent all possible combinations of rolling a die and spinning a spinner with
torisob [31]

I'm assuming the die is 6 sided. The number of leaves required to show the outcome would be the number of ways you can get any number on the die times the number of ways you can pick a number on the spinner. That would be 6*8=48. I'm also assuming you're talking about the final outcome because the answer varies on whether you start with spinning the spinner or rolling the die.
