Suppose that each time Giannis Antetokounmpo shoots a free throw, he has a 3/4 probability of success. If Giannis shoots three f

GREYUIT [131]

Answer:

84.38% probability that he succeeds on at least two of them

Step-by-step explanation:

For each free throw, there are only two possible outcomes. Either Giannis makes it, or he does not. The free throws are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

He has a 3/4 probability of success.

This means that $p = \frac{3}{4} = 0.75$

Giannis shoots three free throws

This means that $n = 3$

What is the probability that he succeeds on at least two of them

$P(X \geq 2) = P(X = 2) + P(X = 3)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{3,2}.(0.75)^{2}.(0.25)^{1} = 0.4219$

$P(X = 3) = C_{3,3}.(0.75)^{3}.(0.25)^{0} = 0.4219$

$P(X \geq 2) = P(X = 2) + P(X = 3) = 0.4219 + 0.4219 = 0.8438$

84.38% probability that he succeeds on at least two of them

What is the perimeter, P, of a rectangle that has a length of x + 5 and a width of y − 1?

Helen [10]

Answer:P=2x + 2y + 8

Step-by-step explanation: Perimeter (p) =2L+ 2w

P= 2(x+5)+2(y-1)

Remove bracket

P=2x+ 10 +2y - 2

P=2x+2y+8

Frank devised a formula for his catering business that calculates the number of meatballs he needs to prepare. The formula is m=

NeX [460]

So if m=4a+2c is your equation then all you have to do is plug in the numbers.

So you then get m=4(25)+2(7), for 25 adults and 7 children.

Then you solve. m=100+2(7)
m=100+14
m=114
So Frank will need 114 Meatballs for the party of 25 adults and 7 children
Hope this helps! And if you need anything else just ask :)
