A and B are two events.

svlad2 [7]

Answer:

A and B are not independent events because P(A|B)≠P(A)

is the correct answer.

Step-by-step explanation:

If A and B are independent then we must have

P(AB) = P(A) P(B) and also

P(A/B) = P(A)

We are given that

A and B are two events.

Let P(A)=0.5 , P(B)=0.25 , and P(A and B)=0.15 .

P(A/B) = P(AB)/P(B) = 0.15/0.5 = 0.3

i.e. P(A/B) is not equal P(A)

Similarly P(B/A) = P(AB)/P(A) = 0.15/0.25 = 0.6 not equal to P(B)

Hence A and B are not independent.

Joshua spends 25 minutes of each day reading. Let d be the number of days that he reads, and let m represent the total minutes o

zavuch27 [327]

Answer:

The number of days are independent and the total number of minutes are dependent.

The required model for the situation is $m=25d$

The table is shown below:

Step-by-step explanation:

Consider the provided information.

Joshua spends 25 minutes of each day reading. Let d be the number of days that he reads, and let m represent the total minutes of reading.

We need to determine which variable is independent and which is dependent.

Here, the number of days are independent and the total number of minutes are dependent.

If he spends 25 minutes each day. So the total number of minutes in d days are:

$m=25d$

The required model for the situation is $m=25d$

Now make the table which showing the number of minutes spent reading over 7 days.

Substitute the value of d from 1 to 7 in $m=25d$

Number of days(D) Minutes(M)
