8.1 8. I selected the king 6 out of 20 times, or 30%. 9. I guessed correctly 16 times, or 32%. 10. I guessed correctly 21 times, or 42%. 11. 28 out of 50 were both black, or 56%. 12. 24 out of 50, 48%. 8.2 8. 11 out of 30 times, or 36%. The odds of this happening are the same as for the second reunion scenario. 26. There are four equally likely scenarios: THH, HHT, HTH, HHH so there is a 25% chance they are all heads. 27. The possibilities are TTH, THT, HTT, HHT, HTH, THH, HHH. There is a 1/7 chance they were all heads. 28. 20/50 cards are face cards, so 40% chance. 30. There are 3 red sides. 2 of the red sides have red on the back and the other has blue. Therefore, there is a 1/3 chance the other side is blue. 35. The two options are mutually exclusive so they may not overlap. He says that there is in total 110% of possibilities. He will likely get below a 4.0. 8.3 15. Just because something can go wrong doesn’t mean it will. It could be a coincidence that many good or bad things happen in a row, just as when many coins are flipped you may get head or tails in a row. 23. I think the probability would be .1^7 or one in 10 million. 8.5 26. Around 400 would have A, 300 B, 200 C, 100 D. A. B. C. D.

27400X.2= 80 A 300X.5=150 of B. 200X.1= 20 C. 100X.3= 30 of D. 28. 80/280= 29%A 150/280=54%B 20/280=7% C 30/280=11% Neither

29. A= 1000X.5X=500 500x.05= 25 Juliasaurus B= 1000X.15= 150 150X.3=45 Maxxasaurus C= 1000X.35=350 350X.10=35 New dino...
