Answer: Our required probability is 0.618.
Step-by-step explanation:
Since we have given that
Probability of all drivers were involved in a car accident last year = 66%
Number of drivers = 10
Number of drivers involved in a car accident = 3
So, probability of drivers involved in car accident is given by
Probability of getting 3 or more who were involved in a car accident is given by
P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)
Here,
So, our equation becomes
P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)
Hence, our required probability is 0.618.
Answer:
0.6384
Step-by-step explanation:
Given that:
10-mg Atorvastatin Placebo Headache 15 65 No headache 17 3
Hence the total of number of patients = 15 + 65 + 17 + 3 = 100 patients
The number of patients with headache = 15 + 65 = 80 patients
Also, C(n, x) is the number of combinations in which n items can be chosen taken x at a time it is given by the formula:
The the probability that if two different subjects they both had a headache = 
Answer:
2/3
Step-by-step explanation:
Even numbers are 2,4,6,8,10,12,14
Multiple of 3 ( other than 6,12 ) are 3,9,15
P=10/15 (simplify by 5)
P=2/3
