Step-by-step explanation:
Order of Operations, Division goes first, then Addition.

First, we need to find out how many siblings the students have in total and how many siblings the teachers have in total.
The students: (1 x 4) = 4 + (2 x 7) = 18 + (3 x 5) = 33 + (4 x 2) = 41. The students have a total of 41 siblings.
The teachers: (1 x 3) = 3 + (2 x 2) = 7 + (3 x 4) = 19 + (4 x 5) = 39 + (5 x 3) = 54 + (6 x 1) = 60 + (8 x 1) = 68. The teachers have a total of 68 siblings.
Now that we have this information, we know that the answer is option 1, the students tend to have fewer siblings than the teachers. This is because the students had a total of 41 siblings and the teachers had a total of 68 siblings, and 41 is less than 68 so the students have fewer siblings than the teachers.
I really hope I could help! I put a lot of work into this answer! :D

Answer: Our required probability is 0.7273.
Step-by-step explanation:
Since we have given that
Actually successful Actually failure Total
Predicted successful 0.4 0.15 0.55
Predicted failure 0.1 0.35 0.45
Total 0.5 0.50 1
Probability that the market research firm would predict that it would be success.
P(Actual success|Predicted success) is given by
Hence, our required probability is 0.7273.
So I assume that 8% is for every sale and meaning he would have to sell 11 sales to get 88% and then that multiplied by 35000 gets you to 30800 and add that by 35000 will get you to 65800 which is more than 65000
