Question

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?

1 over 49
1 over 16
1 over 14
1 over 2

Answer 1

The probability is going to be combined

(probability of red spinner) x (probability of green card)

Answer 2

I was thinking it was a 1/2 chance because you could spin and it could land on green and you could also pick up a green card so there is a chance that you could get green

Answer 3

hmmm

I do agree that the chance of picking the green card is 1/2

but I think the chance of getting red on the spinner is a different probability

Answer 4

So is it A?

Answer 5

no, I don't think it would be A

chance of getting red on spinner = \(\large \frac{1}{7}\)
chance of getting green card = \(\large \frac{1}{2}\)

chance of both = \(\large \frac{1}{7}\times\frac{1}{2}\) = ?

Answer 6

oh I got it now its 1/14 if you multiply 1/7 and 1/2

Answer 7

you got it! :)
