Suppose according to past data for a small boutique, about 30% of the customers who walk into the store purchase at least one it

sashaice [31]

Answer:

Step-by-step explanation:

Let X be the no of customers who purchase atleast one item.

X is binomial since there are two outcomes and each customer is independent of the other.

a) Here n =10

Out of 10 customers we expect np = 3 customers to buy at least one item.

b) exactly 3 of the customers would purchase at least one item

= $P(X=3)=10C3(0.3)^3(0,7)^7\\=0.2668$

c) the probability that no more than 3 customers would purchase at least one item

= $P(X\leq 3)\\= 0.6496$

Evaluate. 15 + 102 • [12 – (12 – 3 • 2)] + 6

mylen [45]

Answer:

633

Step-by-step explanation:

We have the equation

$15+102[12-(12-3*2)]+6\\\\15+102[12-(12-6)]+6\\\\15+102[12-(6)]+6\\\\15+102[6]+6\\\\15+612+6\\\\633$

The probability that an egg on a production line is cracked is 0.01. Two eggs are selected at random from the production line. F

musickatia [10]

Answer:

$P(X \geq 1)=1-P(X$

$P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801$

And replacing we got:

$P(X \geq 1) = 1-0.9801 = 0.0199$

Step-by-step explanation:

Let X the random variable of interest "number of craked eggs", on this case we now that:

$X \sim Binom(n=2, p=0.01)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(x \geq 1)=1-P(X$

And we can find the probability:

$P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801$

And replacing we got:

$P(X \geq 1) = 1-0.9801 = 0.0199$
