A game consists of spinning arrow which comes to rest pointing at one of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12; as shown below.If the outcomes are equally likely, find the probability that the pointer will point at: (i) 6 (ii) an even number

Solution:

We have,

Total number of possible outcomes = 12

(i) Number of favorable outcomes for 6 = 1

Hence, P(the pointer will point at 6) = 1/12

(ii) Favorable outcomes for an even number are 2, 4, 6, 8, 10, 12

So, number of favorable outcomes = 6

Hence, P(the pointer will be at an even number) = 6/12 = ½
