A spinner with 9 equal sections labeled with the letters A, A, B, B, B, C, C, C, and D is spun 198 times. Which of the following correctly predicts how many times the spinner will land on the letter B?
2/5
7/10
66 times
180 blue marbles
82 times
Based on the given information, the spinner has a total of 9 sections, with 3 of them labeled with the letter B.
Therefore, the probability of landing on the letter B is 3 out of 9, or 3/9, which simplifies to 1/3.
To predict the number of times the spinner will land on the letter B in 198 spins, we need to multiply the total number of spins by the probability of landing on B:
198 spins x 1/3 = 66 spins
Therefore, the spinner is expected to land on the letter B approximately 66 times.
