## anonymous one year ago 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?

pls help

6. anonymous

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

o hi

9. anonymous

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

10. anonymous

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

11. anonymous

12. anonymous

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

13. anonymous

Well, I have a final exam to do so bye :)

14. anonymous

bye

15. anonymous

is dat a good explanation?

16. anonymous

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

17. anonymous

where did you get 1/2 from? :)

18. anonymous

0.5 = 1/5

19. anonymous

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

20. anonymous

no that isn't correct. but dont worry. well keep going till you get the right answer

21. anonymous

:(

22. anonymous

lets look at the problem again.

23. anonymous

im not good at math

24. anonymous

jeese how much are you typing?

25. anonymous

you still here?

26. anonymous

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?

27. anonymous

1/7 for the pie and 1/2 for ze plate

28. anonymous

yes exaclty

29. anonymous

great job!

30. anonymous

A)1/49 B)1/16 C)1/14 D)1/2

... sry forgot to put this at the beggining

32. anonymous

hmm. okay. lets use what we have already.

33. anonymous

that confused me a little hmm...let me think for a second

34. anonymous

with the two added together itd be 2/9 lol...hmm

luigi pls halp

38. Luigi0210

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

OH MY GOD WHY DIDNT I THINK OF THAT AGGGHHH

40. anonymous

im having an off day today xD

@TuringTest

48. anonymous

would it be 1//14

49. anonymous

1/14~

50. anonymous

Yep definitely 1/14 :)

51. anonymous

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