<u>Question</u> :
Gabriel has a candy box containing 9 chocolates candies and 12 lollipops. If he choose 2 of them at random.
a) What is the probability that he gets 2 lollipops?
b) What is the probability that he gets 2 chocolates?
c) What is the probability that he gets at least 1 lollipop and 1 chocolate?
<u>Answer</u>:
First we need to calculate the total no. of items. In this case it is the no. of chocolate candies + the no. of lollipops which is, 9 + 12 = <u>21</u>.
Now we can solve the questions.
a) P (2 lollipops) = <u>2/21.</u>
b) P (2 chocolates) = <u>2/21.</u>
c) P (at least 1 lollipop & 1 chocolate) = <u>2/21</u>.
Note : P(x) is read as probability of getting x is....
