ANSWER

The Percentage decrease is
$45\%$

EXPLANATION

The initial value
$20 \: miles$

The final value
$= 11 \: miles$

The percentage decrease can be calculated using the formula,

$Percentage \: decrease \: = \frac{final \: value - inital \: value}{initial \: value} \times 100\%$

We substitute the values to obtain,

$Percentage \: decrease \: = \frac{11 - 20}{20} \times 100\%$

This will simplify to,

$Percentage \: decrease \: = \frac{ - 9}{1} \times 5\%$

$Percentage \: decrease \: = - 45\%$

The negative sign is just there to indicate decrement.

Therefore the percentage decrease is
$45\%$

Theoretical probability: Green

Step-by-step explanation:

25 total

5 red

7 blue

10 green

3 yellow

50 times

It would make sense that the 10 green marbles has the best chance of getting picked. Since you didn't provide any information on the experimental probability, then I can only answer the theoretical one.
