Acoin is tossed n times and we count the number of tails m and the number of heads n-m. let the random variable y be the difference between the number of heads and the number of tails in the n tosses of a coin, i.e., y=(n-m)-m. assume p({h})= p. a) what are the possible values of y? b) find the probability of y=0 c) find the probability of y=2k. d) find the probability of y=2k+1. hint: your answers in parts b), c), d) should depend on whether n is even or odd

If the highest temp. it will get in the day is 75 and it is 56 then all u do is 75-56 to get 19, so it will increase 19 degrees if it gets to 75 degrees during the day.
