You roll a six-sided die twice. What is the probability of rolling an even number and then an odd number? A) 1/4 B) 1/6 C)1/9 D) 1/12

B) 1/6

Step-by-step explanation:

If you roll a six-sided die twice the two times you roll you have a chance of getting an odd number the first time and an even number the second time.

Than would look like 2/12.

2/12 simplified is equal to 1/6.

So,this means the answer is 1/6.

Hope this helps!

1/3

Step-by-step explanation:

This is a compound event. Your sample space consists of {red and 1, red and 2, red and 3, red and 4, red and 5, red and 6, red and 1, red and 2, red and 3, red and 4, red and 5, red and 6, black and 1, black and 2, black and 3, black and 4, black and 5, black and 6} You are looking for an odd number and a red chip. So there are 18 possibilities and 6 of them are what you are looking for. The correct answer is  

1

3

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.
