const2013 [10]

Answer: by using Poisson distribution

The warranty for a particular system on a new car is 2 years

P(x=2)= 0.143

There is no limit to the number of warranty claims per car

P(X=0) = 0.449

Step-by-step explanation:

step:-1

A random variable X is said to follow a Poisson distribution if it assumes only non-negative values and its probability distribution is given by

P(X=x) = $\frac{e^{-w}w^{x} }{x!}$

here w>0 is called the parameter of the distribution

Step 2:- Given mean value of Poisson distribution = 0.8

The warranty for a particular system a new car is 2 years

P(X=x)=P(X=2)= $\frac{e^{-0.8}{0.8^{2} } }{2!}$

P(x=2)= 0.143

Step 3:-

Given mean value of Poisson distribution = 0.8

There is no limit to the number of warranty claims per car

P(X=x)=P(X=0)= $\frac{e^{-0.8}{0.8^{0} } }{0!}$

P(X=0) = 0.449

A college graduate is applying for a job and has 3 interviews with google. she passes the first, second, and third interviews wi

Usimov [2.4K]

The probability she failed the interview is: 1 - probability she passed the interview. P( failed 1st interview) = 1 - 0.9 = 0.1 P(failed 2nd interview) = 1 - 0.8 = 0.2. P(failed 3rd interview) = 1 - 0.7 = 0.3 So we have that if she didn't get the job, the probability that she failed the second interview is 0.2
