Answer:
0.45% probability that they are both queens.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes
The combinations formula is important in this problem:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes
You want 2 queens. Four cards are queens. I am going to call then A,B,C,D. A and B is the same outcome as B and A. That is, the order is not important, so this is why we use the combinations formula.
The number of desired outcomes is a combinations of 2 cards from a set of 4(queens). So
Total outcomes
Combinations of 2 from a set of 52(number of playing cards). So
What is the probability that they are both queens?
0.45% probability that they are both queens.
So, y-intercept is (0,3) and x-intercept is (3/7,0)
Step-by-step explanation:
We are given:
We need to find y-intercept and x-intercept
Finding y-intercept
To find y-intercept we put x =0
Solving:
So, y-intercept is (0,3)
Finding x-intercept
To find x-intercept we put y =0
Solving:
So, x-intercept is (3/7,0)
So, y-intercept is (0,3) and x-intercept is (3/7,0)
