Question

A barrel contains only apples and oranges. There are twice as many apples as oranges. The apples are either red or yellow, and 4 times as many apples are red as are yellow. If one piece of fruit is to be drawn at random from the barrel, what is the probability that the piece drawn will be a yellow apple? Give answer to the nearest tenth.__________%

Answer 1

Let the value of yellow apples be x.
Then there will be 4x red apples because there are 4 times as many red apples as are yellow.
So x+4x=5x which is the total number of apples.
and since there are twice as many apples as oranges that means there will be 5x/2 oranges

So the total amount of fruit there is is, 5x/2+5x=15x/2
Let's calculate the probability now
Probability of picking out the yellow apple-> x/(15x/2) -> \[x\] so it will give you 2/15

thank you!!
