In a power outage rona has to reach into her closet in the dark to get dressed. she is going to find one shirt and one pair of pants. she has three different pairs of pants hanging there: one black, one brown, and one plaid. she also has two different shirts: one white and one polka dot. what is the probability that she will wear both polka dot shirt and plaid pants?

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.

60: 45 =12: 9 =4: 3 so the answer is 4: 3
