Mrs. Larson washed 2/5 of her laundry. Her son washed 1/4 of it. Who washed most of the laundry? How much of the laundry still needs to be washed? ). Write in a fraction

Mrs Larson washed the most Laundry, and there are 7/20 left to wash

Step-by-step explanation:

by multiplying to common denominator 20, 8/20>5/20. for second questions just use 1 - 8/20-5/20 we get 7/20. Done!

2 is the final ! : )

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.
