A box contains 14 40W lamps, 28 60W lamps and 58 25W lamps, all the lamps being of the same size and shape. Three lamps are drawn at random from the box. Determine the probability of:
(i). getting one 25W, one 40W and one 60W lamp, with replacement.
(ii). Getting either one 25W and two 40W or one 60W and two 40W lamps with replacement.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
