1.30 × 3 = 3.90

3.90 + 0.65 (half of 1.30) = 4.55

the most 104 can be devided by 4.55 with no remainders is 22

22 × 4.55 = 100.1

this leaves with 3.9$ which we can buy 3, 1.30 with

22 + 3 = 24

25 tarts is the most you can buy with 104$ leaving on remainders.

Answer:

He has $\frac{-1}{7}$ number of points

Step-by-step explanation:

We have given that numbers from 3 to 9

So numbers will be 3,4,5,6,7,8,9

Here prime numbers are 3,5,7

And composite numbers are 4,6,8,9

So probability of getting prime number = $\frac{3}{7}$

And probability of getting composite number $=\frac{4}{7}$

It is given that if he gets prime number then he get 1 point and if he get composite number then he loss 1 point '

So value of number of point he has = $1\times \frac{3}{7}-1\times \frac{4}{7}=\frac{-1}{7}$
