Example 1 Find the probability of getting a head when a coin is tossed once. Also find the probability of getting a tail. Total number of outcomes = 2 (either Heads or Tails) Number of outcomes in which head comes = 1 P(getting a Head) = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠 𝑖𝑛 𝑤ℎ𝑖𝑐ℎ ℎ𝑒𝑎𝑑 𝑐𝑜𝑚𝑒𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠) = 𝟏/𝟐 Number of outcomes in which tail comes = 1 P(getting a Tail) = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠 𝑖𝑛 𝑤ℎ𝑖𝑐ℎ 𝑡𝑎𝑖𝑙 𝑐𝑜𝑚𝑒𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠) = 𝟏/𝟐
