6. Theoretical vs. Experimental  After 10 spins, Hank landed on green 3 times, red 2 times, orange 1 time, purple 3 times, and yellow 1 time. What is the THEORETICAL probability Hank’s next spin will land on GREEN? RED? What is the EXPERIMENTAL probability Hank’s next spin will land on GREEN? RED?
