A laptop lock has a 4 digit combination. Each character can be any digit between 0-7. The only restriction is that all 4 charact

4088 are possible combinations .

<u>Step-by-step explanation:</u>

Here we have , A laptop lock has a 4 digit combination. Each character can be any digit between 0-7. The only restriction is that all 4 characters cannot be the same (e.g. 0000, 1111, 2222,... etc.). We need to find  How many combinations are possible .Let's find out:

The first digit has 8 choices (can be all of them), the second digit also has 8 choices. The third and fourth digits also have 8 choices.

Multiply them together you get:

⇒ 8(8)(8)(8)

⇒ 4096  possible combinations.

But since all 4 characters cannot be the same, we subtract 8 from 4096 (there are 8 combinations which the 4 characters are the same: 1111, 2222, 3333, 4444, 5555, 6666, 7777, and 0000) and we get :

⇒ 4096-8

⇒ 4088

Therefore, 4088 are possible combinations .

Approximately 13.2% of US drivers are younger than age 25, with 37.7% in the 25-44 age group, and 49.1% in the 45-and-over-categ
Elan Coil [88]

Answer:

could not be the same

Step-by-step explanation:

Given that approximately US drivers are agewise as follows:

<25   13.2

25-45   37.7%

>45   49.1%

Observations are made for a sample of 200 fatal accidents.

Let us create hypotheses as

H_0:  Proportions age wise are the same as for US drivers\\H_a: Proportions are different

(Two tailed chi square test at 5% significance level)

Age <25 25-45 >45  

Expected 13.2 37.7 49.1 100

Observed 42 80 78 200

Expected no  26.4 75.4 98.2 200

Chi square 9.218181818 0.280636605 4.155193483 13.65401191

df = 2

p value = 0.001084

Since p <0.05 we reject null hypothesis

At the  0.05 level, the age distribution of drivers involved in fatal accidents within the state could not be the same as the age distribution of all US drivers as there seems to be significant difference.
