How many red draws can you expect if the ties are pulled out 1,000 times?
200
250
450
550

Answer 1

The experimental probability of a red draw is given by:
\[\large P(red)=\frac{number\ of\ red\ draws}{total\ number\ of\ draws}\]
The expected number of red draws after 1000 ties are pulled out is:
\[\large P(red) \times 1000=you\ can\ calculate\]
