The dimensions of a rectangle are 3 1/5 cm by 5 5/6
Question 4 options: A 9 13/0 cm2
B 21 3/4 cm2
C 18 2/3 cm2
D 12 3/8 cm2

eighteen and two thirds

Step-by-step explanation:

first find a common denominator for your fractions so you can multiply them (Area of a rectangle = Length x Width). you should get (after making everything fractions) 96/30 by 175/30. multiply these. you should get a big number (16800/900) divide and simplify. 18.666e is equal to 18 and 2/3

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.
