Question

Ankit bought 2 packs of red pens, 1 pack of blue pens and 3 packs of black pens. The red pen packs
have 4 pens each. The blue pen packs and the black pen packs have 3 pens each. He places all his
pens in a pen holder. What is Ankit's probability of picking a red pen from the pen holder?​

Answer 1

Answer:

number of red pens = 4(2)= 8

number of blue pens = 1(3) = 3

number of black pens = 3(3) = 9

probability of picking red pen = expected/total = 8/20 = 0.40

chance of picking a red pen = 40%
