Answer:
0.789
Step-by-step explanation:
Number of beef flavored Ramen noodles = 10
Number of chicken flavored Ramen noodles = 10
Total number of noodles = 20
Number of ways to select 3 packages:

= 45
Number of ways to select one chicken flavored Ramen noodle = 10

Formula for probability of an event E can be observed as:

Required probability is:

It looks like a vertical line that intersects the x-axis at x=-0.5.
It's on the left side of the y-axis.
The answer is D because The ordered pairs graphed are (2,3), (6,9), and (8,12). They all have a ratio of 2 to 3. Which means each point is 2 larger on the x-axis and 3 larger on the y-axis than the previous point. The point that is missing is (4,6) since 2 + 2 = 4 and 3 + 3 = 6.
