A bag contains lemon-flavoured candies only. Hema takes out one candy without looking into the bag. What is the probability that she takes out an orange-flavoured candy ?
Suppose there are x candies in the bag.
Then, number of orange candies in the bag = 0.
And, number of lemon candies in the bag = x.
Let E1 be the event of getting an orange-flavoured candy.
∴ P(getting an orange-flavoured candy) = P(E1) =`("Number of outcomes favourable to" E_1)/"Number of all possible outcomes"`
Thus, the probability that Hema takes out an orange-flavoured candy is 0.
