the following are the probabilities of selecting iteams from a bag (candy: grape ?, cherry 3/8, apple 1/4). What is the probability of selecting grape?

they have to add up to 8/8

To find the probability of selecting grape, you need to look at the provided probabilities and determine the probability of selecting grape from the bag. In this case, only the probability of grape is missing.

Given the probabilities of the other items in the bag:
- Cherry has a probability of 3/8
- Apple has a probability of 1/4

Let's assume the probability of selecting grape is represented by P(grape). Since the overall probability of selecting all the items from the bag must add up to 1, we can set up the equation:

P(grape) + P(cherry) + P(apple) = 1

Substituting the given probabilities:
P(grape) + 3/8 + 1/4 = 1

Now, let's solve the equation to find the probability of selecting grape:

P(grape) = 1 - (3/8 + 1/4)
P(grape) = 1 - (6/16 + 4/16) [Finding a common denominator]
P(grape) = 1 - (10/16) [Simplifying the fractions]
P(grape) = 6/16
P(grape) = 3/8

Therefore, the probability of selecting grape is 3/8.
