Answer:
1. 0.1795
2. 0.1693
3. 0.1657
4. 0.1606
Step-by-step explanation:
This problem was solved using the binomial distribution
1.
N = 30
P = 6/30 = 0.2
Using binomial distribution
30C6 x 0.2⁶ x 0.8²⁴
= 593775 x 0.000064 x 0.004722
= 0.1795
2.
N = 60
P = 6/60 = 0.1
60C6 x 0.1⁶ x 0.9⁵⁴
= 50063860 x 0.000001 x 0.00338139
= 0.1693
3.
N = 100
100C6 x 0.06⁶ x 0.94⁹⁴
= 1192052400 x 0.000000046656 x 0.00297864
= 0.1657
4.
Poisson distribution was used here
e^-6(6)⁶/6!
= 0.1606
Answer:
1.77
Step-by-step explanation:
Laura has been running at a rate of 12 miles per week.
Step-by-step explanation:
Given,
Time period = 3 weeks
Distance ran by Laura in 3 weeks = 36 miles
To find distance covered in one week, we will divide the total distance by number of weeks.
Distance covered in one week =
Distance covered in one week = 12 miles
Laura has been running at a rate of 12 miles per week.
