Question

In a bag of apples there are 4 green apples and 2 red apples. Bethany takes a green apple out of the bag and does not replace it. She then takes another apple out of the bag. What is the probability that the second apple is red?

Answer 1

Answer:2/5 = 40%

Explanation:

Bethany already one green apple out, and we have 3 green apples and 2 red ones, so, if we want to know what is the probability that the second apple is red we will apply the follow formula: x/n, being X the favorable cases and n the total of cases, in this problem X is 2, because we want to now the RED apples, and N is the total of apples, being n = 2 red apples + 3 green apples = 5, the formula now looks like this: 2/5=? , we resolve it by doing the division and multiplying for 100, (2/5)100 =40 and now we add a % symbol, (2/5)100=40%, and that´s the answer!
