Sophie [7]

Answer:

There are 78 apples in the bushel that are not granny smith apple.

Step-by-step explanation:

We are given the following in the question:

Number of apples in the bushel,n = 104

Probability of a granny smith apple from The bushel = 25%

P(Granny smit apple) =

$p=0.25$

Thus, probability thta the apple is not a granny smith apple is

P( Not a granny smit apple) =

$q=1 - p = 1-0.25 = 0.75$

Number of apples that are not granny smit apple =

$=q\times n\\=0.75\times 104\\=78$

Thus, there are 78 apples in the bushel that are not granny smith apple.
