Given two spinners divided into three equal parts. The first spinner is numbered 1- 2- and 3. The second spinner is numbered 4 - 5 - and 6.
a. If each spinner is spun once, what is the probability that the product of the two numbers spun is even?
b. What is the probability that the sum of the two is even?
Combinations and probabilities of three-numbered spinners are investigated.
