It’s either 100/729 or approximately 13.72%

Answer:

Probability is : [tex]\frac{100}{729}[/tex]

Step-by-step explanation:

A basket contains four apples and five peaches.

Total number of fruits = [tex]4+5=9[/tex]

Probability of apple being selected = number of apples / total number of fruits = [tex]\frac{4}{9}[/tex]

Probability of peach being selected = number of peaches / total number of fruits = [tex]\frac{5}{9}[/tex]

As replacement is allowed, the probability of selecting an apple in the any attempt will remain [tex]\frac{4}{9}[/tex] and the probability of selecting a peach will remain [tex]\frac{5}{9}[/tex]

So, the required probability will be :

[tex]\frac{4}{9}\times \frac{5}{9}\times \frac{5}{9}[/tex]

= [tex]\frac{100}{729}[/tex]
