The explanation is given below.
Step-by-step explanation:
Given:
Two events take place.
Let event A be flipping a coin
Let event B be rolling a 6-sided die.
Now, a coin has two faces; one is head and the other is tail.
So, the possible outcomes of event A are: {H, T}
H → Head, T → Tail.
Now, a six sided die has six faces each marked with a number. The numbers marked ranges from 1 to 6.
So, the possible outcomes of event B are {1, 2, 3, 4, 5, 6}
Now, each element of set A should match with all the elements of set B.
Now, tabular form should have a row of outcomes of B and a coum of outcomes of event A. Thus,
Outcomes 1 2 3 4 5 6
H H1 H2 H3 H4 H5 H6
T T1 T2 T3 T4 T5 T6
Therefore, the organised list has the following outcomes:
H1 T1
H2 T2
H3 T3
H4 T4
H5 T5
H6 T6
Finally, the correct tree diagram is attached below.

Answer:
Step-by-step explanation:
Assuming this question: "Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to one more decimal place than the largest number of decimal places given in the data. 2,3,4,5,6,7,8,9,10,11 "
Solution to the problem
The range is defined as and if we replace we got:
Now we can calculate the population mean with this formula:
And if we replace we got:
The population variance is given by:
And after replace we got:
And the population standard deviation would be just the square root of the variance and we got:
