Show a way to count from 170-410

Solution:

We need to count from 170 - 410

We have many number of way to count from 170 - 410

But we will show a way only.

2 times count by 100 and 4 times count by 100

170 + 100 = 270                 (Count by 100)

270 + 100 = 370                (Count by 100)

370 + 10 = 380                 (Count by 10)

380 + 10 = 390                 (Count by 10)

390 + 10 = 400                  (Count by 10)

400 + 10 = 410                   (Count by 10)

From 170 count 2 times 100 and 4 times 10 to get 410

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

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.
