SOLUTION

CORRECT QUESTION

There are 150 Steel utensils, 20 aluminium utensil and & 80 glass utensils in a Kitchen. An utensils choosen at random . Find probability that choosen utensil is not of Steel

EVALUATION

It is given that there are 150 Steel utensils, 20 aluminium utensil and & 80 glass utensils in a Kitchen

So total number of utensils in the kitchen

 = 150 + 20 + 80

 = 250

So the total number of possible outcomes = 250

Let A be the event that choosen utensil is not of Steel

Now the total number of utensils not of Steel

 = 20 + 80

 = 100

So the total number of possible outcomes for the event A is 100

Hence the required probability that the choosen utensil is not of Steel

 =   \sf{P(A)}

 \displaystyle \sf{ =  \frac{100}{250} }

 \displaystyle \sf{ =  \frac{2}{5} }
