Group work: Independent/Dependent and Conditional Probability
In a multiple choice exam, there are 5 questions and 4 choices for each question (a, b, c, d). Nancy has
not studied for the exam at all and decides to randomly guess the answers. What is the probability that

question 11. there are y amount of people total, each ticket costs $8 each. this hints us to multiplication or division. if we wanted to find the price for each we would divide, but we want to find the total price so we would multiply 8 and y giving us the equation 8y. making b the correct answer.

question 12. the sum of 5 and another number are separate from three, 5 and another number hints that these to are together (although this may not always be the case depending on the wording). so we have the equation 3(x+5). making the correct answer a.

question 13. much like question 12 it says the product of 4 and another number. product means we will multiply them and the and shows these are the two being multiplied, making the first half of the equation would be 4x. it then says it is increased by 7 so we would at 7 to this, making our final equation 4x+7. therefore our answer is c
