We know that,
Probability of occurrence of an event
= \(\frac{Total\,no.of\,Desired\,outcomes}{Total\,no.of\,outcomes}\)
Total no. of outcomes = 10 + 25 = 35
Desired outcomes are prizes. Total no. of desired outcomes = 10
Therefore, the probability of getting a prize = \(\frac{10}{35}\) = \(\frac{2}{7}\)
Conclusion: Probability of getting a prize is = \(\frac{2}{7}\)
