Select the following statements that are true. The number of bit strings of length n that start with a 1 bit is 2" - 2. The number of different ways to select a president and a vice president from a group of n people is n(n − 1). The number of different ways to divide 6 people into two teams of 3 each to play a 3X3 basketball game is 10. The number of positive integers less than 2625 that are divisible by either 4 or 6 is 1093. P(n,r) = r! · C(n,r). .
