104/ 8 = 13.
Every hour she vacuumed 13 cars.
Answer:
0.0433
Step-by-step explanation:
Since we have a fixed number of trials (N = 25) and the probability of getting heads is always p = 0.05, we are going to treat this as a binomial distribution.
Using a binomial probability calculator, we find that the probability of obtaining heads from 8 to 17 times is 0.9567 given that the con is fair. The probability of obtaining any other value given that the coin is fair is going to be:
1 - 0.9567 = 0.0433
Since we are going to conclude that the coin is baised if either x<8 or x>17, the probability of judging the coin to be baised when it is actually fair is 4.33%
The answer is 6(x^2 -1) I have provided a picture with my work and the answer
Answer:
Membership selection a town council has members Democrats and Republicans if the president and vice president are selected at random what is the probability that they are both Democrats
There is a 26.9% chance, if the president and vice-president are selected at random, that they are both Democrats. There is a 12.2% chance, if a 3-person committee is selected at random, that Republicans make up the majority.
Step-by-step explanation:
is that supposed to be written as a fraction and you are looking for a percentage?
