Answer:
825
Step-by-step explanation:
Let the number of students who participated in the sport be x, which is equivalent to 0.825
The total number of students in the school is equivalent to 1
Expressing mathematically,we obtain
0.825:x=1:1000
By cross multiplying we obtain,
We finally simplify to arrive at
Hence the number of students who participated in the sport is 825

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.
