Answer:
Part 1)
10,000 different numbers.
Part 2)
A) 1 in 10,000.
Step-by-step explanation:
Part 1)
Since there are four digits and there are ten choices for each digit (0 - 9) and digits can be repeated, then we will have:
![T=\underbrace{10}_{\text{Choices For First Digit}}\times\underbrace{10}_{\text{Second Digit}}\times\underbrace{10}_{\text{Third Digit}}\times \underbrace{10}_{\text{Fourth Digit}} = 10^4=10000](https://tex.z-dn.net/?f=T%3D%5Cunderbrace%7B10%7D_%7B%5Ctext%7BChoices%20For%20First%20Digit%7D%7D%5Ctimes%5Cunderbrace%7B10%7D_%7B%5Ctext%7BSecond%20Digit%7D%7D%5Ctimes%5Cunderbrace%7B10%7D_%7B%5Ctext%7BThird%20Digit%7D%7D%5Ctimes%20%5Cunderbrace%7B10%7D_%7B%5Ctext%7BFourth%20Digit%7D%7D%20%3D%2010%5E4%3D10000)
Thus, 10,000 different numbers are possible.
Part 2)
Since there 10,000 different tickets possible, the chance of one being the correct combination will be 1 in 10,000.
This is equivalent to 0.0001 or a 0.01% chance of winning.

Declan has 9 dimes and 8 quarters in his pocket.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of dimes and y represent the number of quarters.
A dime is worth 10 cents. A quarter is worth 25 cents.
Hence:
x + y = 17 (1)
Also:
10x + 25y = 290 (2)
From equation 1 and 2:
x = 9, y = 8
Declan has 9 dimes and 8 quarters in his pocket.
