(Houston, TX, USA)

I need help for some questions below:

Pls, show me steps by steps .

1) I don't know how to write a matrix to display the information in Finite math.

2) Solve the matrix for X .

A=

**[5 3 ,B=[[-6**

8 5 ] -2]], AX=B.

3) Write the indicated event in set notation for the experiment described as :

A die is tossed twice with the tosses recorded as an order pair. Represent the following events as a subset of the sample space: the first toss shows a six.

4) A die is tossed twice with the tosses recorded as an order pair.Represent the following events as a subset of the sample space: The sum of the tossed is either three or four.

5) A die is tossed twice with the tosses recorded as an order pair. Represent the following event as a subset of the sample space: both tosses show an event number.

6) A die is tossed twice with the tosses recorded as an ordered pair. Represent the following event as a subset of the sample space : The second toss shows a two.

7) How to find the percent of the area under a normal curve between the mean and 2.41 deviations from the mean?

8) How to find the percent of the area under the standard normal curve between Z=0.54 and Z=1.91.

9) How to find a Z-score satisfying the given condition.

4% of the total area is to the right of Z.

10)How to find the standard deviation.
