Answer: 0.633 approximately

Step-by-step explanation:

Divide the number of times blue came up (114) over the number of spins total (180). Ignore the 60% given to you. That's a theoretical value that doesn't play any part in determining an experimental probability.

114/180 = 0.633 approximately

The '3's go on forever. Round that however your teacher instructs.
