The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
For a fair coin flip n=28 times we have the following distribution:
We want to find this probability:
Using the probability mass function we got:
And adding the probabilities we got:

Sorry i need to see answers, so i need to answer questions
Step-by-step explanation:
Answer:
(0, 7 )
Step-by-step explanation:
Where the line crosses the y- axis the x- coordinate of the point is zero.
Substitute x = 0 into the equation and evaluate for y
y = - 3(0) + 7 = 0 + 7 = 7 ⇒ (0, 7 )
Answer: 165
Step-by-step explanation:
Given
The shop has 1323 bamboo flowers
Each vase can hold exactly 8 bamboo flowers
no of the vase(n) filled with 8 flowers are
i.e. 165 is completely filled and 166th is partly filled
i.e. 3 flowers are left after filling 165 vases completely.
