Question
34 pens are there in a box where 10 are red pens,
‘p’ are blue pens and remaining are black pens. If a pen is picked, the probability of getting blue pen is 0.5. Find the ratio of the number of blue pens and black pens.Solution
Probability of getting a blue pen , => p/34 = 1/2 => p = 17 So, number of black pens = 34 – 10 – 17 = 7 Required ratio = 17 : 7Â
