Step-by-step explanation:
Powerhouse of photo synthesis
let the line between 2 tria be y
sin 60/8√2 = sin 90/y
y=13.06
sin 45/13.06 = sin 90/x
x=18.46
The number of throws that the player make X follows binomial distribution.
The probability that the player makes x throws out of eleven throws is

The probability that the player makes at most nine out of eleven free throws
is

Correct choice is (B).
