Jacob spins the spinner 120 times.

There are 6 color options.

Therefore, for 1 round we have the next probability to land on red:

1/6

Now, for 120 rounds, we can find the solution when we multiply the probability for one round by 120 rounds.

Hence,

(1/6)*120 = 20

So, he can expect at least 20 times to land on red.
