Suppose the probability is 0.25 that any given person will believe a rumor about the private life of a certain politician. what is the probability that the fifth person to hear the rumor will be the first one to believe it?

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
