Pls hellppp Jennifer wants to visit 4 different cities A, B,C and D on her vacation. If she will visit them one at a time, and completly random, what is thr probabitly that she will visit them in the exact order ABCD or DCBA?

The probability that she will visit them in the exact order ABCD or DCBA =  

Step-by-step explanation:

Given: Jennifer wants to visit 4 different cities A,B,C and D on her vacation.

If she visits in an order , total such orders will be = 4 x 2 x 3 x 1 =24.

Since probability =

In this case favorable outcomes ( ABCD ,  DCBA)=  2

Total outcomes = 24

Required probability =

Hence, the probability that she will visit them in the exact order ABCD or DCBA =  

1) is right

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
