I have a random question.
Lets say you were flipping a weighted coin that gets tails only 3.5% of the time.
What are the odds of: Getting tails 2/18, and what are the odds of getting tails 3/18 times, and what are the odds of tails 4/18 times?
For reference, 0 is roughly 52.65%, and 2 is about 34.35%, so 2+ is 13%, just wanna know the distribution.

Also, these dumb frickers can't get the order of operations right. Do you really expect them to grasp the nuances of probability?

3.5%=3.50%
You're welcome.

Just plug in the values to the probability mass function for a binomial distribution. Number of trials = 18 and the success probability = 0.035.
The number of successes k is 2
The number of successes k is 2

Use the coin to buy beer.

So what does the odds show up for 2/18 and 3/18?

So you want the probability of getting 2 out of 18 flips to be tails, right?
K=2, p=0.035, n=18

Can you just give me the answers? lol. What are the odds of 2/18 exactly and what are the odds of 3/18 exactly
Posted on 10/27/17 at 7:17 pm to LordSaintly
yup, binomial distribution, thanks for saving me the time of pulling that formula up
