Daytime high temperatures in New York in February are normally distributed with an average of 30.2º and a standard deviation of
8.5°.
Estimate the probability that the temperature on a given day in February is 22° or lower.
a. 0.23
b. 0.48
c. 0.815
d. 0.16

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.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
