Best ResponseYou've already chosen the best response.0Well there are 7 equal colors, so that makes the probability of choosing one 1/7. They want to know what are chances of choosing red AND getting a green card.. and there are two cards so that's 1/2. Just multiply them and it should give you what you need \[\large \frac{1}{7} (chance~ of ~it~ landing~ on ~red) * \frac{1}{2} (chance ~of~ getting~ a~green ~card) \]
