Answer:

0.016

Step-by-step explanation:

To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.

Therefore, the formula of probability is

P(v) = \frac{no of events}{total possible outcomes}\\

In the given case,

P(v) = \frac{20}{1250}\\ P(v) = 0.016

Which is our required answer.
