Two matrices are called equal matrices if they have the same order or dimension and the corresponding elements are equal.

Suppose A and B are the matrices of equal order i × j and aij = bij, then A are B are called equal matrices.

Example: Find the value of a and x if the matrices

[

−

]

[

−

]

are equal.

Solution:

Given that,

A = B

[

−

]

[

−

]

Since A and B are equal matrices the corresponding elements are equal.

Therefore,

a = 4

x – 6 = 3

x = 3 + 6

x = 9

babymother [125]

Answer:

Step-by-step explanation:

The total number of bags in the bottle = 20 + 15 = 35

Then

the probability that the first bag is blue = 20/35

If we replace the first bag :

the probability that the second (picked) bag is blue = 15/35
