Step-by-step explanation:
For the first song, it is certain it isn't a duplicate. For the second song, the probability that it is not a duplicate is 4999/5000. The probability the third song is not a duplicate is 4998/5000.
Hence the probability that none of the 100 songs is a duplicate is ...
5000!/4900!/5000^100 ≈ 0.369120
Then the probability that one or more is a duplicate is ...
1 - 0.369120 ≈ 0.630880
Answer:
39 degrees (ABC)
Step-by-step explanation:
The whole of the angle shown (ABD) = 107 degrees
EBD = 34
Since BE bisects CBD, both CBD and EBC are equal (half of 68)
107 - 68 = 39
ABC = 39
