Answer:
3.6 repeating or 3 and 2/3
Step-by-step explanation:
I did the work on a calculator.
Answer:
The probability mass function is expressed as:
P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]
Step-by-step explanation:
This is not a binomial distribution. It is actually a negative binomial distribution. The probability mass function is expressed below:
P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]
where:
x = number of failures
r-1 = number of successes (10 in this scenario)
p = probability of a success
nCr = n!/[r!(n-r)!]
The main formula difference in the positive binomial versus negative binomial is this: With respect to the negative binomial, it is obviously known that the last event will be: when we reach our 10th "head", we stop .
Thus, the last flip will ALWAYS be a "head".
Two hundred eighty one million four hundred eighty thousand one hundred
The answer is 66.
Explanation
4×3 = 12,
6×9 = 54.
54+12 = 66
To do this the first box on the left corner it says three and four so you multiply them. Then there’s a second box with six and nine. You have to multiply 6 and 9 together. After you get those answers you add that answer with the answer from three times four.
Hope I helped you!
