In a certain game of chance, a wheel consists of 48 slots numbered 00, 0, 1, 2, …, 46. To play the game, a metal ball is spun around the wheel and is allowed to fall into one of the numbered slots.(a) The sample space is . (b) The probability that the metal ball falls into the slot marked 4 is . (round to four decimal places). (c) If the wheel is spun 1000 times, it is expected that about of those times result in the ball landing in slot 4. (give a whole number). (d) The probability that a metal ball lands in and odd slot is (round to four decimal places)
