and 
.
The slope of the line is
So by the point slope formula the equation of the line is
When 
we have 
.
Therefore the line joining the two points cuts the y-axis at (0,-2).
Answer:
No. See explanation below.
Step-by-step explanation:
Since the cards are being selected <u>without replacement,</u> every time we select a card, <u>the probability varies</u> (since there is one less card) and therefore, the probability doesn't remain the same for every trial and therefore, the probability of success changes for every trial.
It is because of this that this probability experiment doesn't represent a binomial experiment.
