When six basketball players are about to have a free-throw competition, they often draw names out of a hat to randomly select the order in which they shoot. What is the probability that they shoot free throws in alphabetical order? Assume each player has a different name.
P(shoot free throws in alphabetical
order)=?
(Type an integer or a simplified fraction.)
Six basketball players randomly select the order in which they shoot in a free-throw competition.
Let us first calculate all the possible combinations in which the players can arrange them for the throw.
Hence, the total number of possible combinations in which the players can make throws is 6*5*4*3*2*1 = 6!
It is given that each player has a different name. If we arrange them all in alphabetical order then there is a unique combination in which they can be arranged.
According to the empirical definition of probability of an event,
where n(A) is the number of ways an event A can occur and n(S) is the total number of possible events.
P(shoot free throws in alphabetical order) = = = 0.0013888 = 0.014
Hence, the probability that the players shoot free throws in alphabetical order is 0.014.
