Answer:

-1

Step-by-step explanation:

This is the slope because x is the slope, and if there is no number in front of x then x is 1. There is also a negative in front of x which means the answer is -1.

Michael Beasley is shooting free throws. Making or missing free throws doesn't change the probability that he will make his next

Elodia [21]

Answer: C. $0.75^4$

Step-by-step explanation:

Let x be the binomial variable that denotes the number of makes.

Since each throw is independent from the other throw , so we can say it follows Binomial distribution .

So $X\sim Bin(n=4 , p=0.75)$

Binomial distribution formula: The probability of getting x success in n trials :

$P(X=x)=^nC_xp^n(1-p)^{n-x}$ , where p = probability of getting success in each trial.

Then, the probability of Michael Beasley making all of his next 4 free throw attempts will be :

$P(X=4)=^4C_4(0.75)^4(1-0.75)^{0}$

$=(1)(0.75)^4(1)\ \ [\because\ ^nC_n=1]\\\\=(0.75)^4$

Thus, the probability of Michael Beasley making all of his next 4 free throw attempts is $=0.75^4$

Hence, the correct answer is C. $0.75^4$ .
