Let \(E\) be the event “drawing a red marble” from a bag of 10 marbles with 6 red marbles. Let \(F\) be the event “spinning a 1” on a spinner numbered 1 to 10.
Suppose the two events are independent.
  1. Draw the probability tree diagram.
  2. Calculate the probability of "drawing a red marble" and "spinning a 1".
