Answer 2

Answer: option (a) - 2

Step-by-step explanation:

there are balls till 30 and numbers less than 30 in which all balls are taken into consideration

so probability = 30 / 30 = 1 = P

there are no balls more than 30 so

probability = 0 / 30 = 0 = Q

from 1 - 10 there are 5 odd numbers so from 1 - 30 there will be 15 odd numbers so

probability = 15 / 30 = 1 / 2 = R

it is given to find (P+Q) / R

=> (1 + 0) / 1 / 2 = 1 * 2 = 2

so required answer is 2
