Answer:
p(win)=0.00094
Step-by-step explanation:
-This is a factorial/combination question.
-The probability is calculated using the formula:

Where:
is the number of successful picks
is the total number of picks
Therefore, we calculate the probability as follows;

Hence, the probability of winning is 0.00094
Answer:
m = -5/2
Step-by-step explanation:
Solve for slope with the following equation:
<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(4 , -12) = (x₁ , y₁)
(-2 , 3) = (x₂ , y₂)
Plug in the corresponding numbers to the corresponding variables:
<em>m </em>= (3 - (-12))/(-2 - 4)
<em>m</em> = (3 + 12)/(-2 - 4)
<em>m </em>= (15)/(-6)
Simplify the slope:
<em>m</em> = -(15/6) = -5/2
-5/2 is your slope.

It's closed under addition. You can take any two natural numbers you want, add them up and you'll get some other natural number (eg: 3 and 5 ---> 3+5 = 8)
it's not closed under subtraction. Sure 5-3 = 2 is a natural number but 3-5 = -2 is not a natural number
so that leads us to the answer being choice B
