    There 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. = \[\frac{ 5 }{ 15 } * \frac{ 4 }{ 14 }\]

    okay, 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

    if she replaces the chip then the probability will remain the same, so it is 5/25 * 5/25 = 25/625 because the events are still dependent.

    there are 36 possibilities. only 2 of those possibilities will give you a total of 11 so you have 2/36 =

    ignore the equal sign at the end, the answer is 2/36

    just use the methods I showed you in my solutions, it's the same question with different values.
