Find the sum of the two matrices:

5 2
3 0
+
4 1
6 7
=
a b
c d

9 ... 3

9 ... 7

Step-by-step explanation:

Given

Matrices A and B

Let A ,=

5 2

3 0

And B =

4 1

6 7

Two matrices must have an equal number of rows and columns to be added.

As seen above, the two matrices have 2 rows and 2 columns, so they can be added together

To as these two matrices, we add corresponding rows and columns only.

Take for instance, matric A is represented by

a11 .. a12

a21 .. a22

And

Matric B is represented by

b11 .. b12

b21 .. b22

Their sum can be represented as follows

a11 + b11 .. a12 + b12

a21 + b21 .. a22 + b22.

So, the result of the question, using the above illustration is

a = 5+ 4

b = 2 + 1

c = 3 + 6

d = 0 + 7

So, the matrix becomes

9 ... 3

9 ... 7

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
