Two nonperpendicular lines line TG and line SF intersect at B so that B is between T and G, and B is also between S and F. Tell whether the statement is true. 10. angle TBF is congruent to angle SBG.

11. angle TBF is congruent to angle TBS.

12. M<TBS + M<GBF = 180°

its 4 because 2 times 2 is 4, if you double the number two you get four

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.
