Alright today is day#4 of this fun questions time, but you also need to think What is it:
You have to guess the number that is in my mind
(Hints: It is between 10 and is a odd number)

Rules:
You can't just answer randomly to get points (please)
Pick a number out of 10 and thats it.

What you get?

- If you guess the right answer, you get mark as braniliest and get 10 points and get 5 stars + a thanks for the answer. (I think you will get 3 points if you get marked as brianiliest)
- If you guess it wrong, you get 10 points and 5 stars + thank for the answer

Note:
- This is will happen every day, but sometimes it might not happen, but watch out for it.
- I might not mark you as brianiliest or see your answer very quickly, but if i see a answer later, i will go have a look, if it is right or wrong, you will get the rewards.

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
