Best ResponseYou've already chosen the best response.1Probability first bulb is red = 14/29 There are not 13 red bulbs left and 28 total bulbs left Probability second bulb is red = 13/28 p = 14/29 * 13/28 = 13/58 = 0.224 2) Probability first bulb is red = 14/29 Probability second bulb is yellow = 8/28 p = 14/29 * 8/28 = 4/29 = 0.138 3) Probability first bulb is yellow = 8/29 Probability second bulb is red = 14/28 p = 8/29 * 14/28 = 4/29 = 0.138

Best ResponseYou've already chosen the best response.2probability of first bulb being red is 10/29... if that one is taken out, you have 28 bulbs left total and 9 red bulbs left, probability of second ball being red is 9/28. since it's first AND second bulb being red, you have 10/29 * 9/28 = probability of both being red
