    There are

    26C2 = 26! / (24! * 2!)

    = 26 * 25 / 2 = 325 ways to draw two red cards.

    There are

    26C3 = 26! / (23! * 3!)

    = 26 * 25 * 24 / (3 * 2) = 1300 ways to draw three black cards.

    325 * 1300 = 422,500 ways to draw two red and three black cards.

    a. sixty 5,780 strategies There are 26 red playing cards once you commence, and each and each and every time you draw one, there is one a lot less. There are 5! orders in which an same set of 5 playing cards would properly be drawn. (26 x 25 x 24 x 23 x 22) / (5 x 4 x 3 x 2 x a million) = 7,893,600 / 120 = 65780

    red cards = 26 of them

    black cards = 26 of them

    ways of drawing 2 red cards = 26*25 since there can't be any repeats.

    ways of drawing 3 black cards = 26*25*24

    ways of drawing 2 red AND 3 black

    (26*25) * (26*25*24)

    This assumes that drawing a red 10 of hearts first and then a red 10 of diamonds second counts as one way and then drawing them in reverse counts as well as another way. If this is not the case, the Samwise's answer is correct
