If you decide to play a pick 3 lottery game, in which you have to guess the exact order of the three numbers, what is your probability of winning? all 3 numbers will be between 0 and 9 and can be chosen more than once. a. 1/100 b. 1/1000 c. 3/1000 d. 1/720

Correct choice is B

Step-by-step explanation:

1. You have the only chance to guess the exact order. Hence, the number of favorable outcomes is 1.

2. All three numbers can be chosen among 10 dogits (from 0 to 9) and can repeat, then the number of all possible outcomes is

3. The probability to win is

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
