Wolverine may be a member of the X-Men but they don't always share enemies. Charles Xavier and Wolverine are trying to prioritise which villains to concentrate their powers on (i.e. shared enemies).. Since we are trying to shade ONLY the intersection of these two sets, we finish our diagram by darkly shading the overlap of the two sets, and erasing the parts of sets A and B that are not in the ov Simulation.

Their data suggest that about 8% of the customers who buy tickets are no-shows. Wanting to avoid empty seats and avoid missing an opportunity to increase revenue, they decide to sell 17 tickets for each flight. Ticketed customers who can’t be seated on the plane will be accommodated on another flight and will receive a certificate good for a free flight at another time. Design and carry out a simulation to estimate the probability that at least one ticket-holder is denied a seat on the plane if 17 tickets are sold..
