50 Jorge tardó 4 minutos en correr 1/2 milla. ¿Cuánto tiempo le llevará
correr 3 millas? *
28 minutos
24 minutos
12 minutos
6 minutos
2 minutos
1,5 minutos

24 minutos.

Step-by-step explanation;

Si Jorge tarda 4 minutos en correr media milla, entonces tardará 8 minutos en correr una milla. Entonces, tardaría 24 minutos en recorrer las 3 millas.

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.
