Assuming that X is a binomial random variable with n = 10 and p = 0.25, find the probability, P for each of the following values

seropon [69]

Answer: a) 0.0584

b) 0.2816

c) 0.1877

d) 0.1877117

Step-by-step explanation:

The binomial probability formula :-

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

Given : X is a binomial random variable with parameters :-

n = 10 and p = 0.25

$\text{a) P(x=5)}= ^{10}C_{5}(0.25)^5(0.75)^5\\\\=252(0.25)^5(0.75)^5\approx0.0584$

$\text{b) P(x=2)}= ^{10}C_{2}(0.25)^2(0.75)^8\\\\=45(0.25)^2(0.75)^8\approx0.2816$

$\text{c) P(x=1)}= ^{10}C_{1}(0.25)^1(0.75)^9\\\\=(10)(0.25)^1(0.75)^9\approx0.1877$

$\text{d) P(x=9)}= ^{10}C_{9}(0.25)^1(0.75)^9\\\\=(10)0.25)^1(0.75)^9\approx0.1877117$

The manager of a gas station has observed that the times required by drivers to fill their car's tank and pay are quite variable

Nat2105 [25]

Answer:

The probability that a car driver can complete the transaction in less than 5 minutes is 0.4647.

Step-by-step explanation:

Let X = times required by drivers to fill their car's tank and pay.

The average time required by drivers is, β = 8 minutes.

The random variable X is Exponentially distributed with parameter, $\lambda=\frac{1}{\beta}=\frac{1}{8}=0.125$ .

The probability distribution function of exponential distribution is:

$f_{X}(x)=\lambda e^{-\lambda x};\ x>0$

Compute the probability that a car driver can complete the transaction in less than 5 minutes as follows:

$P(X$

Thus, the probability that a car driver can complete the transaction in less than 5 minutes is 0.4647.
