A spinner has 14 equal sectors with different letters for each sector as shown below Victoria spins to spend 18 times and it stops at the B 10 times if she spends to spend a 19th time, what is the theatrical probability that this time it will stop at the B?
The theoretical probability of the spinner stopping at the letter B is calculated by finding the ratio of the number of favorable outcomes (stopping at B) to the total number of possible outcomes.
Given that the spinner has 14 equal sectors and stops at B 10 times in 18 spins, the probability of stopping at B is:
P(B) = number of times spinner stops at B / total number of spins
P(B) = 10 / 18
P(B) = 5 / 9
So, the theoretical probability of the spinner stopping at B on the 19th spin is 5/9.
