Answer 8

o hi

Answer 9

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

Answer 10

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

Answer 11

explain your answer ;)

Answer 12

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

Answer 13

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

Answer 14

bye

Answer 15

is dat a good explanation?

Answer 16

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

Answer 17

where did you get 1/2 from? :)

Answer 18

0.5 = 1/5

Answer 19

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

Answer 20

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

Answer 37

luigi pls halp

Answer 38

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

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