In this problem, it is said that a professional basketball player can make a free throw on a given trial with a probability equal to 0 .87.
00:08
This player shoots two free throws, and we need to determine the probability that the player can make at least one free throw.
00:16
So let us consider f to be the event of the basketball player making a free throw.
00:22
Then according to the question, the probability of this event f is 0 .87.
00:27
From here, we can determine the probability of f complement, which is the probability that the player does not make a free throw.
00:34
Using the complement rule of probability, this is equal to 1 minus p of f.
00:39
So that's 1 minus 0 .87, and this is equal to 0 .13.
00:45
Now, what we have been asked to determine is the probability that the player can make at least one free throw.
00:55
Using the complement rule of probability, this is equal to 1 minus the probability of the probability of the probability.

The complementary event...
