Using it's concept, it is found that the probability of guessing the right combination in one try’s is of
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 4 dials, each with a
probability of getting it correct, hence the probability of getting the right combination is given by:

Answer:
3 x 5
Step-by-step explanation:
The dimension of a matrix is normally represented in form of:
<u>number of rows</u> x <u>number of columns</u>
In the given matrix, there are 3 rows and 5 columns.
=> The dimension of this matrix is 3 x 5
=> Option D is correct

Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made =
= 30
Answer: Second option is correct.
Explanation:
Since we have given that

And 
To find the remainder, we use the Remainder Theorem, which states that when f(x) is divided by (x-c) then the f(c) is the required remainder.
So,
Here, we have,

So, we will find f(-2) which will give us the required remainder,

Hence, Second option is correct.
