The probability of randomly selecting a cream filled
Chocolate is 1/4
- Probability is the likelihood of an event will occur
- Probability of an event is find out by divide the number of favorable outcomes by the total number of possible outcomes.
- The simplest example is flipping of a coin.
- There are only two possible outcomes when you flip a coin. It wiil be either heads or tails.
- Total probability is always lie between 0 and 1
Let E be the event of selecting cream filled chocolate.
Number of favourable outcome = 6
Total number of possible outcome = 24
Probability if selecting a cream filled chocolate = 6/24
= 1 / 4
Hence, the probability of randomly selecting a cream filled chocolate is 1/4
