Choose a number that will produce an irrational answer when added to . Choose from among these four numbers: , , 0.404040..., 0.286. Complete each step to help you make your choice. Step 1: Identify the type of number that is given. The number is a(n) (rational / irrational) number. (1 point) Step 2: Identify the type of answer that is desired. A(n) (rational / irrational) number answer is desired. (1 point) Step 3: Identify the rule that applies. Fill in the blank with rational or irrational. This rule applies: rational + = irrational. (1 point) Step 4: Identify the type of number that must be chosen based on the rule. A(n) (rational / irrational) number must be chosen based on the rule. (1 point) Step 5: Identify the required number from among the choices and give a reason for your answer. will produce an irrational answer when added to , because . (2 points)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
