tall is the building to the nearest foot?
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.
b) 1/3 * 1/5
step-by-step explanation:
each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
step-by-step explanation:
there are 36 inches in a yard
25 : 36 = 0.69 yards (you can round to 0.70)
