A Find the measurements below in the form
ax 10, where I the density of air at 27°C and 1 atm
pressure, 0.00161 g/cm3
b the radius of a calcium atom,
0.000 000 000 197 m
c one light-year, 9460 000 000 000 km
d the mass of a neutron,
0.000 000 000 000 000 000 000 001 675 g.

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.
