Answer:
72
Step-by-step explanation:
Stage A has 6 outcomes, then B has 4 and C has 3
Take for example only 1 outcome of A, it will have 4 outcomes of B and each outcome of B will have 3 outcomes.
Then a single outcome of A has a total of 12 outcomes (4*3)
Writing it in a way A, B, C:
1,1,1
1,1,2
1,1,3
1,2,1
1,2,2
1,2,3
1,3,1
1,3,2
1,3,3
1,4,1
1,4,2
1,4,3
This is only taking in consideration 1 outcome of A, A has a total of 6 outcomes.
The total of outcomes in the experiment = 6*12=72
Answer: 1%
Explanation:
Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000
There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.
Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%
