The name of 6 boys and 7 girls are written on cards you pull 1 out without replacing it and you pick another one what is the probability of picking 2 cards with the girls name

The probability of picking two cards with the girls name with out replacement

Step-by-step explanation:

Explanation:-

The number of cases that two cards can be drawn  from '6' boys and '7' girls one after another with out replacement.

That is

Let 'E' be the event of the pick another one of two cards from girls name with out replacement .

That is total number of girls =7

The number of ways cases that the two cards can be drawn one after another one without replacement = = 42

Required probability P(E) =

Conclusion:-

The probability of picking two cards with the girls name with out replacement

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.
