Answer:
9.52% probability of getting both candies green
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the candies are selected is not important. They are also selected without replacement. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Find the probability of getting both candies green
Desired outcomes:
2 green, from a set of 5. So
[tex]D = C_{5,2} = \frac{5!}{2!3!} = 10[/tex]
Total outcomes:
2 from a set of 4+5+6 = 15. So
[tex]T = C_{15,2} = \frac{15!}{2!13!} = 105[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{10}{105} = 0.0952[/tex]
9.52% probability of getting both candies green
