We have the table of the number of apples versus the number of trees:
Number of apples Number of trees
15 1
24 2
25 4
If X is the number of apples, we can calculate the expected number of apples per tree by adding all the apples counted and dividing them by the number of trees counted.
[tex]\bar{X}=\frac{15+24+25}{1+2+3}=\frac{64}{6}\approx10.67[/tex]Answer: the expected number of apples per tree is approximately 10.67 apples.
