In a jar, there are (x + 8) red balls, ‘x’ blue balls, and (x + 2) black balls. If the probability of picking two blue balls at random is (1/45), then find the value of ‘x’.
According to the question, Total number of balls in the jar = (x + 8 + x + x + 2) = (3x + 10) According to the question, 
Since the number of balls cannot be negative, Therefore, x = 5
