    The probability of ordering turkey P(T) = 0.55 The probability of ordering ham P(H) = 0.305 The probability of ordering neither turkey nor ham is \[\large P(\bar{T} \cup \bar{H})=0.225\] therefore the probability of ordering turkey or ham is \[\large P(T \cup H)=1.000-0.225=0.775\] The probability of ordering turkey and ham can be found from the equation \[\large P(T \cup H)=P(T)+P(H)-P(T \cap H)\] which can be rearranged to give \[\large P(T \cap H)=P(T)+P(H)-P(T \cap H)\ .........(1)\] Plugging values into equation (1) we get \[\large P(T\cap H)=0.55+0.305-0.775=0.08\] The number of the next 1,000 customers who will order both turkey and ham is therefore given by \[\large 1000\times0.08=80\ customers\]
