Answer:
1/4 or 25%
Step-by-step explanation:
The probability for rolling an odd number is 50% or
because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). 
The probability for rolling two odd numbers in a row is

So, the probability of rolling an odd number twice is 25% or
.
The answers is x =3 , x= -10
Answer:
5x^2+x-6
Step-by-step explanation:
(5x-1)(x+1)-5x+x-5+x
(5x^2+5x-x-1)-5x+x-5+x
5x^2+x-6
If we simply it, then it would be
3 + 2x + 6 + x = 15, which equals
3x + 6 + 3 = 15,
3x + 9 = 15,
if we subtract 9 from 15, we get 6. If we divide 3x by 3, and 6 by 3, we get 2.
Therefore x = 2, and we know there is a 10/15 chance to get a humbug, or a 1/3 chance.
Hope this helped.
