Now,
Mean =
------------------------------------------------------------------------
In the case of repeated data , follow the steps given below to calculate the mean :
- Draw a table with 3 columns
- Write down the items ( x ) in ascending or descending order in the first column and the corresponding frequencies in the second column.
- Find the product of each item and it's frequency ( fx ) and write in the third column.
- Find the total of f column and fx column.
- Divide the sum of fx by the sum of f ( total number of items ) , the quotient is the required mean.

Answer:
77%
Step-by-step explanation:
Given the following :
Probability of winning both games = 50%
Probability of winning just the first game = 65%
Let the probability of winning the ;
First game = p(A) = 65%
Second game = p(B)
Both games = p(A and B) = 50%
What is the probability that the team will win the 2nd game given that they have already won the first game
The above question is a conditional probability question :
Probability of winning the second Given that they've already won the first = p(B | A)
p(B | A) = (A and B) / p(A)
p(B | A) = 50% / 65%
p(B | A) = 0.5 / 0.65
p(B | A) = 0.7692307
= 76.9% = 77%
Step-by-step explanation:
(i) From the graph value of x varies -3 to 3 i.e.
and domain in the input values which function can take
So, option (d) is correct.
(ii) option (d) is correct as it represent the function . While all the other function does not satisfy the given conditions.
(iii) are the parts of solution pair.
(iv) Option (c) and (d) represents the function as each element of the first set has a unique image in the second set.
