The probability of an event is expressed as
Given:
The probability of drwing two blue balls one after the other is expressed as
For the first draw:
For the second draw, we have only 1 blue ball left out of a total of 6 balls (since a blue ball with drawn earlier).
Thus,
The probability of drawing two blue balls one after the other is evaluted as
The probablity that none of the balls drawn is blue is evaluted as
Hence, the probablity that none of the balls drawn is blue is evaluted as
Answer:
B
Step-by-step explanation:
A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.
Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.
Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.
-4 as a fraction would be -4/1.
So start at (5,3), go down 4 and over 1, repeatedly and you got it.
**Just remember the rise over run can be confusing with negative slopes.**
Answer:
3rd option
Step-by-step explanation:
Since 8 minutes is included, do the closed circle. He put it in there for 8 minutes, than put it in there for longer which makes the graph go to the right with including the closed circle. Hope this helped!
