(x,y) or
(x,f(x))
so just plug the first value in and see if yo get the 2nd value


A. when x=-2, then is f(x)=48?
remember, x^-m=1/(x^m)
3(1/4)^-2=3/((1/4)^2)=3/(1/16)=3*16=48
true

B. x^0=1
so 3(1/4)^0=3(1)=3
true

C. when x=2
3(1/4)^2, 3(1/16), 3/16

suter [353]

Answer: 0.064

Step-by-step explanation:

Binomial probability formula :-

P(X)=^nC_x \ p^x\ (1-p)^{n-x}, where P(x) is the probability of getting success in x trials, n is total number of trials and p is the probability of getting succes in each trial.

Given : The proportion of the homes constructed in the Quail Creek area include a security system :  p=0.40

Now, if three homes are selected at random, then the probability all three of the selected homes have a security system is given by :-

P(3)=^3C_3 \ (0.40)^3\ (1-0.40)^{3-3}\\\\=(0.40)^3=0.064

Hence, the probability all three of the selected homes have a security system = 0.064
