Answer:
<h2>From least to greatest: C, B and A</h2>
Step-by-step explanation:
To order each Kicker correctly, we have to find the success rate of each one, which is obtained by dividing and then multiplying by 100 to obtained the percentage:
<h3>Success rate of A:</h3>
<h3>Success rate of B:</h3>
<h3>Success rate of C:</h3>
So, comparing all three, from least to greatest we have:
C with 79%, then B with 83%, and A with 86%.
Answer:
Step-by-step explanation:
To see if two events are independent you can use the formula P(a|b) = P(a)
In this problem P(C|Y) = 35/75 = .4667 and P(C) = 110/300 = 3.667,
therefore C and Y are not independent events because P(C∣Y) ≠ P(C).
The answer is choice D
