Formula : Probability = 
From the given frequency distribution for the class level of students in an introductory statistics course, we have
Number of Junior= 12
Number of Senior = 7
Total students = 6+16+12+7 = 41
Probability that the first student obtained is a junior = 
Probability that the the second student obtained is a senior. 
Then, the probability that the first student obtained is a junior and the second a senior would be 
Hence, the required probability is .
<span>import math
def calculateDistance(x1,y1,x2,y2):
dist = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
return dist
distance = calculateDistance(2,4,6,8)

Whats the question that you have and remember theres always google
Answer:
She earns $7.
Step-by-step explanation:
5 percent of 140 is 7. You can think of this as taking ten percent of 140.0 by moving the decimal point one place to the left, 14, and then since 10 divided by 2 is 5, divide that by 2 and you get 7.
Step-by-step explanation:
