A basketball player shoots free throws. the number of free throws made is recorded. Define a random variable so that it is Bernoulli.

Solutions

Expert Solution

Here basketball player shoots free throws:

So each free throw is independent of other. And outcome is dichotomous (either score a goal or miss). This satisfies the condition of Bernoulli distribution

Here Let X be the random variable being number of scores out of n-free attempts by the basketball player

Let p be the success probability of scoring a goal

So q=1-p is the probability of missing the goal

So now probability of the basketball player having k scores out of n free throws is given below:

P (X=k scores) is given by nCk (p)k(q)n-k

A basketball player shoots 3 free throws. On each throw, she has a 70% chance of making the shot. Assume the outcomes of the throws are independent. What is the probability that she makes the first two free throws and then misses the last one?
The basketball player Steph Curry sometimes shoots free throws with his mouthguard in his mouth, and sometimes shoots free throws with his mouthguard outside of his mouth
Curry's mouthThe basketball player Steph Curry sometimes shoots free throws with his mouthguard in his mouth, and sometimes shoots free throws with his mouthguard outside of his mouth. His free throw statistics for one season were:Free throws with mouthguard in: 110 completed, 13 missed (89.4%)Free throws with mouthguard out: 198 completed, 16 missed (92.5%)His observed free throw completion rate was slightly higher when his mouthguard was outside his mouth. However, we should check whether the difference could be plausibly explained...
