CHALLENGE QUESTIONS 1.) Based on the data table, what is the probability of getting anything BUT a ?

2.) Kobe and Ross decide to flip over an additional ten bottle caps each. Kobe predicts that he will reveal at least two puppy paws. Ross predicts that he will reveal at least 2 skull-and-crossbones. Based on the data table, whose prediction is more reasonable and why?

3.) Trena takes all fifty of the bottle caps from the data table and puts them in a sack. Then she randomly removes ten of them. Of the forty remaining bottle caps, the new probability of revealing
