Given that A game of chance consists of spinning an arrow which is equally likely to come to rest pointing number
to find: Probability of following
So, Total numbers on the spin is 12
(i) Now, Favorable outcomes i.e. to get is
Therefore, total number of favorable outcomes i.e. to get is
We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Hence, the probability of getting a
(ii) Now, Favorable outcomes i.e. to get an odd number are and
Thus, total number of favorable outcomes i.e. to get a prime number is
We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Therefore, the probability of getting a prime number
