The player spins the spinner, and the resulting number is the number of seconds he or she is given to solve a word puzzle.

If 100 players are selected randomly, how many players areexpectedto get between 42 and 72 seconds to solve the puzzle?

If 100 players are selected randomly, what is the probability that the number of players who will get between 42 and 72 seconds to solve the puzzle is withintwo standard deviationsof the expected number of players to do so?
