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

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
