Answer #1

A certain basketball player can make a free throw shot 25% of the time.

Thus, p = probability of accurate free throw shot = 0.25

q = probability of incorrect free throw shot = 1-p = 0.75

To find probability that in a sequence of free throw shots this player makes his/her first shot.on the fourth try

n = 4

Thus, he misses 1st , 2nd , 3rd each with probability 0.75 and hits last one correct which has probability 0.25

Thus. required probability = P(1st fail)*P(2nd fail)*P(3rd fail)*P(4th pass)

= 0.75*0.75*0.75*0.25

= 0.1055

A basketball player takes 20 shots per game. The odds of making any single shot are 1 to 3. All shot attempts are independent, i.e. there are no “hot streaks". What is the probability that the player will make 5 or more shots in a game? Hint: First find the probability of making a single shot. Define a random variable X to represent the number of shots made in a game. State a reasonable probability distribution for X. Finally, you...
