CONCEPTConditional ProbabilityReport an issue with this question13Maria flipped a coin 60 times, and the coin came up tails 32 times.What is the relative frequency of the coin turning up headsin thisexperiment? Answer choices are rounded to the hundredths place.0.472.141.880.53RATIONALERecall that, of the 60 flips, there are 32 tails. This means the remaining are heads, or60-32 = 28 heads. The relative frequency of a head is:
CONCEPTRelative Frequency Probability/Empirical MethodReport an issue with this question14Two sets A and B are shown in the Venn diagram below.A= 7 B= 5 overlapping = 5 bottom=3Which statement is FALSE?
Sets A and B have 5 common elements.There are a total of 25 elements shown in the Venn diagram.Set A has 12 elements.Set B has 10 elements.RATIONALETo get the total number of items in the Venn diagram, we add up what is in A and B andoutside, which is 7+5+5+3 =20 elements, not 25 elements.The intersection, or middle section, would show the common elements, which is 5elements.The number of elements of Set A is everything in Circle A, or 7+5 = 12 elements.The number of elements of Set B is everything in Circle B, or 5+5 = 10 elements.CONCEPTVenn DiagramsReport an issue with this question15Jake tosses a coin and rolls a six-sided die.All of the following are possible outcomes EXCEPT:Tails, ThreeTails, OneHeads, SevenHeads, Five
RATIONALERecall a coin has heads and tails and a standard die has six values, {1, 2, 3, 4, 5, or 6}.So, obtaining a value of 7 is not possible.CONCEPTOutcomes and EventsReport an issue with this question16Select the following statement that describes overlappingevents.
