Question

13) The following Venn diagram shows the slx possible outcomes when rolling a fair die Let A be the event of rolling an even number and let B be the event of rolling a number greater than 1 13) Which of the following expressions describes the event of rolling a 17 D) Ac C) AuB B) B Answer the question True or False. 14) Two chips are drawn at random and without replacement from a bag containing two blue chips14) and two red chips. Events A and B are defined as follows A (Both chips are red) B: (At least one of the chips is blue) True or False: A-BC A) True B) False Find the indicated probability. Express your answer as a simplified fraction unless otherwise noted. 15) 15) The following table contains data from a study of two airlines which fly to Small Town, USA Number of flights Number of flights which were late which were on time Podunk Airlines Upstate Airlines 43 If one of the 87 flights is randomly selected, find the probability that the flight selected arrived on time given that it was an Upstate Airlines flight 43 87 43 48 B) A) 76 D) None of the above is correct C)

Answer 1

13) Since 1 is neither an element of A nor and element of B, and ​​​​​​

AC B

Thus the expression which denotes the event of rolling 1 is $B^c$

Option A) is correct

14) Given statement is true

As ​​​​​​

B": {Non of the chips are blue}-(Both chips are red} A

15) There are 43+5=48, Upstate Airlines

And out of them 43, are on time

Hence the required probability is

43

Option C is correct
