MP3 players in the shipment which are likely to be defective is 330.
Step-by-step explanation:
•	Probability is event of an occurrence which is uncertain.
•	Probability always lies between 0 to 1.
•	The sample of 50 MP3 has 6 defective, to solve it has to be converted.
•	Convert percentage in 100 multiply numerator and denominator by 2.
•	Result is 6/50 converted to 12/100, bring it to 0.12%.
•	12% is defected in 100% of sample.
•	It is found here that 2750 is the population and 12% of 2750.
•	2750 * 0.12 = 330, defective pieces in 2750.
•	There are three types of Classical,Empirical or Experimental.
•	Classical are ‘n’ number of events find the probability occurrence.  
•	Empirical or experimental is purely based on events.

Answer:
45
Step-by-step explanation:
3 out of 12 is 1/4, or 0.25, so if you divide 180 by 4, then using the same logic, you can expect 45 kids to have played last year.
3 = 1/4 OR .25 of 12, 12 divided by 4 = 3
180 divided by 4 = 45
