In this problem, it is said that there are 39 chocolates in a box, all identically shaped.
00:05
Some of them are filled with nuts, some with caramel, some are solid chocolate.
00:09
You randomly select one piece, eat it, and then you select a second piece.
00:13
We need to find the probability of selecting two nut candies.
00:16
So let us consider n1 to be the event that the first candy selected is a nut candy, and let us consider n2 to be the event that the second candy selected is a nut candy.
00:26
Now we need to find the probability of n1 and n2.
00:30
Now, using the multiplication rule of probability, this will be equal to p of n1 times p of n2 given n1.
00:39
So what is p of n1? that is the number of favorable outcomes divided by the total number of outcomes.
00:45
Now, the total number of outcomes is the total number of chocolates in the box.
00:48
That is given to be 39...
