A roof contractor determines that he must place the base of his ladder 6 10 points feet away from the house, making an angle of 74 degrees with the
ground. To the nearest tenth of a foot, how far above the ground is the
eave of the roof?

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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

step-by-step explanation:

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
