Which of the following is a counterexample for this conditional statement? If a shape is a rectangle, then its perimeter is an even number.
a a rectangle with sides measuring 3.2 and 5.3
b a rectangle with sides measuring 10 and 7
c a rectangle with sides measuring 3.9 and 5.1
d a rectangle with sides measuring 1.5 and 2.5

y = x + 95

y = 42 + 95

y=137 mm hg

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.
