Given:
8 2/3 hours per month
12 months in a year.
Number of hours she play soccer in a year.
8 2/3 must be converted to improper fraction.
((8*3)+2)/3 = 26/3
26/3 * 12 = (26 * 12)/3 = 312/3 = 104
Yolanda spends 104 hours in a year playing soccer.
I assumed that 3 households are sampled.
Now, is the number in each of these households equal to 1, 3 and 8 people?
Next, the question says, samples of n=2 are randomly selected (with replacement) from these 3.
So are sample space is
11
13
31
33
18
81
38
88
83
88
This is done 9 times.
Is that how you understand the problem?
When they select the household with only 1 person, the variance is 0
When they select the household with 8 people, they variance will be from a discrete uniform distribution
Similarly for household with 3 individuals.

Answer:
946
Step-by-step explanation:
xyz- the searched number where x depicts hundreds, y - tens and z describes ones. Both X and Z are divisible by 3 .Y and Z are divisible by 2
Z is divisible by 3 and divisible by 2, the only digit which is possible is 3*2=6
6-2=4 - tens digit Y
The hundreds place digit is 3*3=9
S0 946- is an answer
