Ex15.1, 6 (Method1) A bag contains lemon flavoured candies only. Malini takes out one candy without looking into the bag. What is the probability that she takes out (i) an orange flavoured candy? Let total number of candies = 100 Number of candies which are orange flavoured = 0 P(candy taken out is orange flavoured) = (๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐๐๐ ๐คโ๐๐โ ๐๐๐ ๐๐๐๐๐๐ ๐๐๐๐ฃ๐๐ข๐๐๐)/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐๐๐ ) = 0/100 = 0 Ex15.1, 6 (Method2) A bag contains lemon flavoured candies only. Malini takes out one candy without looking into the bag. What is the probability that she takes out (i) an orange flavoured candy? The bag contains lemon flavoured candies only. It does not contain any orange flavoured candies. So every time, she will take out only lemon flavoured candies. P (an orange flavoured candy) = 0 Therefore, event that Malini will take out an orange flavoured candy is an impossible event. Ex15.1, 6(Method1) A bag contains lemon flavoured candies only.

Malini takes out one candy without looking into the bag. What is the probability that she takes out (ii) a lemon flavoured candy? Bag has all lemon flavoured candies. So, Malini will take out only lemon flavoured candies. P (a lemon flavoured candy) = 1 Therefore , event that Malini will take out a lemon flavoured candy is a sure event.
