Answer:
0.0023 = 0.23% probability that all 5 balls selected will be the same color
Step-by-step explanation:

is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes:
Either 5 amber from a set of 6, or 5 blue from a set of 5. So

Total outcomes:
5 balls selected from a set of 6 + 5 + 4 = 15. So

Probability:

0.0023 = 0.23% probability that all 5 balls selected will be the same color
