Statistical inference solution creates an efficient use of numerical data connecting to groups of individuals or experiments. It deals with all aspects including the collection, study and explanation like data and planning the collection of data. By statistical inference solution, people can get knowledge after beginning their work in several fields. There is also a regulation known as mathematical statistics, which is related with the theoretical root of this topic.

Below are the facts meant by statistical inference solution:
Suit | Spade | clubs | Hearts | Diamond |
No. of times drawn | 90 | 100 | 120 | 90 |
While a card is tired at random what is the probability that it is
a) To got a diamond cards
b)To got a black cards
c) Except spade
Given:
Total number of events = 90 + 100 + 120 + 90 = 400
a) To got a diamond cards
Number of trials in which a diamond drawn = 90
P (the card drawn is a diamond) = $\frac{90}{400}$ = 0.22
b) To got a black cards
Number of times a black card showed up = 90 + 100 = 190
P (the card drawn is black) = $\frac{190}{400}$ = 0.48
c) Except spade
Number of times a card other than a spade showed up = 100 + 120 + 90 = 310
P (the card is not a spade) = $\frac{310}{400}$ = 0 .78
Let probability of the student who speaks two languages = A
By statistical inference solution,
Here is a step by step explanation by statistical inference solution,
Step 1:
Total number of students = 500
Number of student speaks Hindi, P(H) = 300
Number of student speaks english, P(E) = 350
Step 2:
We know,
P(H $\cup$ E) = P(H) + P(E) - P(H $\cap$ E)
=> 500 = 300 + 350 - P(H $\cap$ E)
=> P(H $\cap$ E) = 650 - 500
= 150
=> Number of students who can speak both languages = 150
Step 3:
Now, a student can selected at random who can speak two languages.
