Find Probability<br />

Date<br />

Suppose you are playing a game with a spinner. Each player spins<br />

the spinner twice. The spinner has four colors: yellow, blue, pink, <strong>and</strong><br />

green. You can make a grid to show all of the possible outcomes of<br />

spinning the spinner. Each outcome is shown where each row <strong>and</strong><br />

column intersect.<br />
