Assume that is an equal chance of the coin landing on heads or tail (the coin is fair, not biased).
Probability of coin landing on head and then on tails=1/2 x 1/2=1/4

Many people were coughing and some were crying, and all looked as though they had been struck by a blow to the head.A few men attempted heroics and tried to go back into the hotel to save those who remained behind, and I think one student did actually rescue an elderly woman who had succumbed to paralysis beside the buffet table; but generally, there was no thought of re-entering the burning building once one had escaped. Indeed, so great was the heat that we in the crowd had to move farther and farther across the street until we all stood in the college quadrangle, surrounded by bare oaks and elms and stately sycamores.Q.
