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) = (๐‘๐‘ข๐‘š๐‘๐‘’๐‘Ÿ ๐‘œ๐‘“ ๐‘œ๐‘ข๐‘ก๐‘๐‘œ๐‘š๐‘’๐‘  ๐‘–๐‘› ๐‘คโ„Ž๐‘–๐‘โ„Ž โ„Ž๐‘’๐‘Ž๐‘‘ ๐‘๐‘œ๐‘š๐‘’๐‘ )/(๐‘‡๐‘œ๐‘ก๐‘Ž๐‘™ ๐‘๐‘ข๐‘š๐‘๐‘’๐‘Ÿ ๐‘œ๐‘“ ๐‘œ๐‘ข๐‘ก๐‘๐‘œ๐‘š๐‘’๐‘ ) = 1/2 Number of outcomes in which tail comes = 1 P(getting a Tail) = (๐‘๐‘ข๐‘š๐‘๐‘’๐‘Ÿ ๐‘œ๐‘“ ๐‘œ๐‘ข๐‘ก๐‘๐‘œ๐‘š๐‘’๐‘  ๐‘–๐‘› ๐‘คโ„Ž๐‘–๐‘โ„Ž ๐‘ก๐‘Ž๐‘–๐‘™ ๐‘๐‘œ๐‘š๐‘’๐‘ )/(๐‘‡๐‘œ๐‘ก๐‘Ž๐‘™ ๐‘๐‘ข๐‘š๐‘๐‘’๐‘Ÿ ๐‘œ๐‘“ ๐‘œ๐‘ข๐‘ก๐‘๐‘œ๐‘š๐‘’๐‘ ) = 1/2
