Step-by-step explanation:

x^2+6x-112=0

(x-8)(x+14)

x=8

x^2+1=65

2x+24=40

4x+43=75

We choose a 4-digit number randomly. What is the probability that all its digits are even? help asap

Vlad1618 [11]

Answer:

It's very simple. In 4 decimal digits there are 10,000 (0000 to 9999) possible values. The odds of any one of them coming up randomly is one in 10,000. A specific "4 digit number" would have 1/9000 chance, since there are 9000 4 digit numbers (1000-9999).
