Question

in a kitchen, there are 54 utensils consisting of bowl, plates and glasses. the ratio of bowl , plate glasses is 3:2:1. a utensil is picked at random.find the probability that:- 1. it is a plate. 2. it is not a bowl.

Answer 1

Total number of utensils = 54

Ratio of bowls, plates, glasses = 3 : 2:1

Bowls = 3, plates = 2, glasses = 1.

1). P = 2 / 54 = 1 / 27

2). Probability of being a bowl = 3 / 54 = 1 / 18

Probability of not being a bowl = 1 - 1 / 18

P' => 17 /18
