A binomial probability experiment is conducted with the given parameters. Use technology to find the probability of x successes in the n independent trials of the experiment. n=9,p=0.25,x<4

Therefore the required probability is 0.83427.

Step-by-step explanation:

Binomial (n,p) distribution:

A discrete random variable X having the set {0,1,2,3.....,n} as the spectrum, is said to have binomial distribution with parameter n=the number of trial in the binomial experiment,p= the probability of success on an individual trial, if the probability mass function of X is given by

for x= 0,1,2,....

               =0                           elsewhere

where n is a positive integer and 0<p<1.

Given that,

n= 9 and p=0.25

We are interested to find P(x<4).

P(x<4)

=P(x=0)+P(x=1)P(x=2)+P(x=3)

≈ 0.83427

Therefore the required probability is 0.83427.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

yes   because as the functions are graphed they eventually will intersect unless otherwise
