10. the probability that a randomly selected student has at least 1 household member who smokes is 0.421. which cell is connected to this probability?
use this probability to calculate the value of that cell.

Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421

Step-by-step explanation:

We assume the following table:

                                   No Hou. smokes     >=1 hou. smokes           Total

Student indicates he           Cell 1                        Cell 2                    Cell 3

or she has asthma

Student indicates he

or she does not have            Cell 4                      Cell5                    Cell 6

asthma

Total                                      Cell 7                         Cell8                   1000

We are assuming a grand total of 1000 people for this case

Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

the eight graders whould be the answer
