Every day, a bakery owner buys either butter(B) or ghee(G).The type of item purchased in consecutive days is to be recorded.List
the sample space.If a different type of item is purchased than in the previous day, we say that there is a switch.Let X denote the
number of switches. Determine the value of X for each elementary outcome.Suppose that for each purpose P(B)=1/2, and the
decision in different days are independent. Assign probabilities to the elementary outcomes and obtain the distribution of X.
