Answer:
The correct answer is 4294967296 possible ways to complete such a test.
Step-by-step explanation:
Step 1
The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are ways to complete the first step,
ways to complete the second step,
, and
ways to complete the
step, this process can be carried out in
ways.
Step 2
We use the fundamental principle of counting with for a total of
steps. This test can be carried out in
ways. This comes from multiplying 4 by itself 16 times.
Given data:
Total number of songs = 8
Rock songs = 3
Reggae songs = 2
Country songs = 3
Probability = Number of favorable outcomes / Total number of outcomes
To find:
When song is selected randomly to play first song and then second song from remaining ones ,
Probability when both the songs are from Reggae songs,
Thus , the probability is 1/28.
