Best ResponseYou've already chosen the best response.0There are 15 marbles at first, 5 are red. after you pick one red marble, there are 4 reds left in a bag of 14 marbles The two events are dependent so you have to multiply them. = \[\frac{ 5 }{ 15 } * \frac{ 4 }{ 14 }\]

Best ResponseYou've already chosen the best response.0okay, sorry. ;n; so you have a 22/50 chance of getting tails and A 20/50 chance of getting a blue marble, the chance of both happening at the same time is 22/50 * 20/50 = 440/2500
