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.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
