Well, how many pieces of fruit are there total?

OpenStudy (gabbyalicorn):

16

OpenStudy (pinklion23):

yea add then all up then subtract the amount of oranges and pears combined

OpenStudy (anonymous):

Right! So you know that the probability will be something out of 16 which will make 16 your denominator. Now, how many pieces of fruit of the sixteen are pears and oranges?

OpenStudy (gabbyalicorn):

1/16

OpenStudy (pinklion23):

no :(

OpenStudy (gabbyalicorn):

OpenStudy (pinklion23):

OpenStudy (pinklion23):

yes C is right but i need to explain so you get it

OpenStudy (freeg13):

7/16

OpenStudy (freeg13):

4 + 3 over 4 + 3 + 9

OpenStudy (anonymous):

You had 16 pieces of fruit originally. So it will be ?/16. How many apples and pears are there in the box?

OpenStudy (gabbyalicorn):

oh no i get it u add the pears and the orages 4+3= 7

OpenStudy (gabbyalicorn):

thank you guys!

OpenStudy (pinklion23):

np

OpenStudy (anonymous):

Perfect! So then you get 7/16 which cannot be simplified whcih means it's your answer.
