1.	In a lottery, there are 10 prizes and 25 blanks. Find the probability of getting a prize.
Answer» 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 = \(\frac{2}{7}\)

Answer»

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 = \(\frac{2}{7}\)
