Ponderosa Paint and Glass carries three brands of paint. A customer wants to buy another gallon of paint to match paint she purc

sveta [45]

Answer:

$\frac{4}{9}$

Step-by-step explanation:

Two events are independent of each other, this is called Compound Probability. Classical example is if two coins are filped, what is the probability of getting two heads in a row.?

Answer: each has 50% probability because there are two states only, either H or T. since we have two coins the probability of getting two heads in row is the product of obtaining heads for each individual coin (which is independent of each other). or is $\frac{1}{2}$ × $\frac{1}{2}$ = $\frac{1}{4}$ = 25%. (Notice!).

Back to our problem, now here we have 3 paint brands and one of them is the right paint brand and two of them are not correct brands. so the prabablity that the customer has picked not correct brand is $\frac{2}{3}$ and her husband has not picked correct brand is also $\frac{2}{3}$ , since two probabilities are compound probabilities i.e indepandant of each other the probablity that both woman and her husband fail get correct brand is the product of the two and is = $\frac{2}{3}$ × $\frac{2}{3}$ = $\frac{4}{9}$ .

Two cars leave towns 360 kilometers apart at the same time and travel toward each other. One car’s rate is 10 kilometers per hou

Goryan [66]

9514 1404 393

Answer:

85 km/h

Step-by-step explanation:

Let s represent the speed of the slower car. Then the travel time is ...

time = distance/speed

2 = 360/(s +(s+10))

4s +20 = 360 . . . . . multiply by 2s+10

4s = 340 . . . . . . . . . subtract 20

s = 85 . . . . . . . . . . . divide by 4

__

The rate of the slower car is 85 km/h.

Which of these is NOT a characteristic of a binomial experiment? A. What happens on one trial affects the probability on the nex

nignag [31]

Answer:

A. What happens on one trial affects the probability on the next: they are dependent events.

Step-by-step explanation:

Below are some important characteristic of a binomial experiment:-

A binomial experiment has n trials.
Each trials has two possible outcomes. Success or failure.
The probability of success is same in very trail.
The event is independent event. In other words, the probability of one event doesn't effect the other.
The coefficient of the binomial term can be determined using Pascal’s triangle

Basis these characteristics, only the first option is not a properties of a binomial experiment. In case of binomial experiment, the event is independent event.

Hence, option A is correct.
