Answer:
The table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
The graph is shown in figure attached.
Step-by-step explanation:
We need to create table and graph the expression:
Table is made, such that we take value of x and find value of y
You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.
So our table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.
The graph is shown in figure attached.
The probability of winning exactly 21 times is:-0.32
Given,
The probability of winning on an arcade game, p = 0.659
Number of times you play arcade game, n = 30
By assuming this as a normal distribution, we get
Mean=μ=30×0.659 =19.77
Standard deviation, σ =
=
≈ 2.60
Let X be a binomial variable
Then, the z score for x = 21 will be:
z = (x - μ) / σ =
≈ 0.47
Now, the probability of winning exactly 21 times
P (x ≥ z) = P (21 ≥ 0.47) = 0.32
Hence the probability of winning exactly 21 times is 0.32
