Question
A game of chance consists of spinning an arrow which is equally likely to come to rest pointing to one of the number, 1, 2, 3, ..., 12 as shown in Fig. below. What is the probability that it will point to 10?
Solution
Total no. of possible outcomes = 12 {1, 2, 3,…., 12}
Let E ⟶ event of pointing 10
No. favourable outcomes = 1 {10}
P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`=1/12
