An inspector examines a large shipment of several thousand laser pointers by randomly selecting and then inspecting 6 laser pointers. suppose that 1% of the laser points are defective. which one of the following expressions describes the probability that exactly one of the six laser pointers is defective?

Step-by-step explanation:

For each laser pointer, there are only two possible outcomes. Eithey they are defective, or they are not. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

In this problem we have that:

Which one of the following expressions describes the probability that exactly one of the six laser pointers is defective?

The probability that exactly one of the six laser pointers is defective can be determine by binomial probability distribution.

The expressions describes the probability that exactly one of the six laser pointers is defective.

Given:

The probability is .

Number of pointers .

Consider the formula for binomial probability distribution.

Where is number of different combinations of X objects from a set of n elements.

Substitute the value in above equation.

Thus, the expressions describes the probability that exactly one of the six laser pointers is defective.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
