HELP ME HOW TO SHOW WORK :,(

$87.71

Step-by-step explanation:

So there is 2 ways you can do this.

1 way is you can just multiply 125.30 by 70% (or 0.7 as it is the same thing), which would get you the right answer because it shows 70% of 125.30.

Or another way is you can find 10% of 125.30, which would just be 1 decimal point to the right, so 12.53, then multiply it by 3 (for the 30%) to get 37.59 and subtract that from 125.30.

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.
