6. 6. PROBABILITY’S CASE * In a bag there is 1 green marbles and 4 blue marbles.
7. 7. 1. When you takes one marble atrandom then how many opportunitiesare being picked green marbles?
8. 8. 1. When you takes one marble atrandom then how many opportunitiesare being picked green marbles?2. When you took one marble atrandom what is the probability that ablue marble is drawn?
9. 9. 1. When you takes one marble atrandom then how many opportunitiesare being picked green marbles?2. When you took one marble atrandom what is the probability that ablue marble is drawn?3. When you take one marble atrandom then what is the probability ofmarbles drawn are green or blue? .
10. 10. ANSWER for question number 1 1 1. Opportunity (green) = 5 = 20%
11. 11. With a simple understanding. There are 5marbles then there are 5 choices takemarbles. Among the ﬁve marbles there isonly 1 green marbles then there is only onegreen choice.
12. 12. So the chances of green chosen is 1possibility out of 5 possible options. Or wecan write: 1 20Opportunity (green) = 5 = 100 = 20%
13. 13. 1What is the meaning of odds 5 this?????The simple meaning is that if you took 1marbles so it is unlikely you will get a greenmarbles. But if you took 1 marbles 5 timesalmost certain you will succeed in green.15 x5 = 1
14. 14. for question number 2 42. Opportunity (blue) = 5 = 80%
15. 15. With a common understanding, there are 4blue marbles marbles out of 5 total. Sochances are the blue you got 4 choice of 5options possible. We can write,Opportunity (blue) = 4 = 100 = 80% 5 80
16. 16. 4What is the meaning of odds 5 this?
17. 17. True. We can guess. Opportunity 4 is almost 5sure that you is almost certainly managed toobtain a blue color. When you took themarbles repeat 5 times then you will be ableto obtain blue green 4 times and only onetime.
18. 18. for question number 33. Opportunity (green or blue)=1+4 5 5 5= 5=1
19. 19. Of course you certainly managed to take themarbles are green or blue. There are 5marbles are green or blue color. So you has 5choices of 5 possible options. your conclusioncertainly succeeded.
20. 20. In the theory of chances, chances aredeﬁnitely going have a chance = 1 = 100%.
21. 21. In fact, the play super marble, we sometimestake the marbles directly 2 points or 3 pointsaccording to the results of dice throws us.
22. 22. *** ***The Other Problem***
23. 23. Case : Taking the ball one by one withreplacement.
24. 24. In a basket there are 7 red balls, 5 blue ballsand the black 8 ball. If 3 balls drawnrandomly drawn ball on condition returned tothe basket, what is the probability that theballs are drawn successively red, black andblue?
25. 25. Because the decision is with replacement,then the number of balls in the basket foreach decision is ﬁxed, namely: 7 +5 +8 =20.
26. 26. So the odds of drawing a ball with asequence of red, black, blue is the product ofthree chance of drawing the ball on everydecision, namely: 7 8 5 7P = 20 x 20 x 20 = 200
27. 27. Case : Taking the ball one by one withoutreplacement.
28. 28. In a box there are 5 red balls, six green ballsand 4 yellow balls. If 3 balls drawn atrandom without replacement, what is theprobability that the ball drawn in a row isred, green, red?
29. 29. Since taking the ball without replacement,then the number of balls in the box on everydecision will be diﬀerent. Chances are themultiplication of each opportunity on everydecision. Can be calculated by: 5 6 4 4P = 15 x 14 x 13 = 19
