In a lottery, there are 10 prizes and 25 blanks. A lottery is drawn at random. What is the probability of getting a prize?
Answer & explanation
Correct answer: option 4
Number of prizes = 10
Number of blanks = 25
Total number of possible outcomes
= Number of prizes + Number of blanks
= 10 + 25 = 35
Now,
Probability of getting a prize = \(\frac{10}{35}\)
= \(\frac{2}{7}\)
