Ex 14.1, 19
A child has a die whose six faces shows the letters as given below:
The die is thrown once. What is the probability of getting
A?
Total number of faces on the die = 6
Number of faces having A on it = 2
P (getting A) = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑓𝑎𝑐𝑒𝑠 ℎ𝑎𝑣𝑖𝑛𝑔 𝐴)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑓𝑎𝑐𝑒𝑠 𝑜𝑛 𝑑𝑖𝑒)
= 2/6
= 𝟏/𝟑

A child has a die whose six faces shows the letters as given below:
The die is thrown once. What is the probability of getting
(ii) D?
Total number of faces on the die = 6
Number of faces having D on it = 1
P (getting D) = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑓𝑎𝑐𝑒𝑠 ℎ𝑎𝑣𝑖𝑛𝑔 𝐷)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑓𝑎𝑐𝑒𝑠 𝑜𝑛 𝑑𝑖𝑒)
= 𝟏/𝟔
