The value of X in the circle C is 1.6 (The 6 is repeated! )
Answer:
It is not a binomial experiment because the random variable associated with this experiment is a Geometric random variable.
Step-by-step explanation:
For an experiment to be a binomial experiment the variable associated with the experiment has to be a binomial random variable.
A binomial random variable should satisfy the following conditions:
- There should be a fixed known no. of trials
- There should be only 2 outcomes of a trial i.e either success or failure
- Trial results should be independent
- Same probability for each trial success or failure
Now lets see what is the random variable in this experiment:
The Random variable would be X = no. of selections until a defective one is found.
X does not satisfy the first condition for a binomial variable itself as the no. of trials is not fixed and is unknown.
Hence X is not a binomial random variable.
Rather X is a Geometric random variable. If we consider finding a defective one as a success then the variable is defined as the no. of trials until a success is achieved. But a binomial random variable is defined by no. of successes in a fixed no. of trials.
Hence it is not a binomial experiment .
First find the circumference of the wheel ( the length around the outside).
Circumference = 2 x PI x Radius
Circumference = 2 x 3.14 x 14 = 87.92 feet.
This would be the distance it traveled in one full rotation.
To find the distance traveled in 96 degrees, multiply total distance by 96/360 ( this is the fraction of a full rotation it travels).
87.92 x 96/360 = 23.4 feet
Answer:2
Step-by-step explanation:..
There are 26 letters, four times. There are 10 numbers, four times. 26x26x26x26=456,976
10x10x10x10= 10,000
Final Answer: 4,569,760,000
