A spinner and 2 cards are shown below: A spinner with 7 equal sectors is shown in the figure. The colors Green, Red, Orange, Violet, Pink, Yellow, and Blue are marked on it. The arrow points at the red color. Two cards are shown on the right side. The colors Purple and Green are marked on. Sophie spins the spinner and picks up a card without looking. What is the probability that the spinner stops at red and a green card is selected?

    probability of landing on red = (number of red sections) divided by (number of total sections on spinner)

    probability of picking green card = (number of green cards) divided by (number of total cards)

    So the probability of picking a green card is 1/5?

    1 divided by 2 is .5 so i made it into a fraction

    that doesnt sound right. you cant make a decimal a whole number.

    0.5 = 1/5

    no...0.5 is 1/2 as a fraction. not 1/5. 0.2 is 1/5 as a fraction

    in fact lets just change its wording up a bit to make it more simple. There 7 pieces of pie and each slice has a different color crust. the colors are Green, Red, Orange, Violet, Pink, Yellow, and Blue. and there are two plates. each a different color. the two colors are green and purple. without looking. sophie picks up a piece of the pie and one of te plates. What is the probability that sophie picks up a red piece of pie and a green plate?

    Well 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 \[\large \frac{1}{7} (chance~ of ~it~ landing~ on ~red) * \frac{1}{2} (chance ~of~ getting~ a ~green ~card) \]

    Since 1/7 * 1/2 equals 1/14
