Atair coin is tossed three times and the events A, B, and G are dened as follows: A : {At least one head is observed } B : {At least two heads are observed } C : {The number of heads observed is odd } Find the following probabilities by summing the probabilities of the appropriate sample points (note that t] is an even number}: (a) P{not A) = (b) P{(not A] and B] = 1. Start by writing the sample space 5 as a set. i Write each of the events A, B and C as sets. i Create a Venn Diagram with the 2 events in part (b) as circles and place each of the outcomes in the appropriate place. Shade the compound event for part (b) and use the Venn Diagram to calculate the answer. 0 Create a Venn Diagram with A, B and C as circles and place each of the outcomes in the appropriate place. Shade what is asked for part {c} and use the Venn Diagram to calculate the
