Which situation describes independent events? a) one student is chosen from classroom a, then a student is chosen from classroom b. b) one card is chosen from a standard deck, it is set aside, then a second card is drawn. c) one student is chosen from classroom a, then a second student is chosen from classroom a. d) tom chooses a letter of the alphabet, then beth must choose a different letter from the alphabet.

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
