Answer:
i)
ii)
And replacing we got:
iii)
Step-by-step explanation:
Let X the random variable of interest "number of inhabitants of a community favour a political party', 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:
Part i
We want this probability:
Part ii
We want this probability:
And we can use the complement rule and we have:
And if we find the individual probabilites we got:
And replacing we got:
Part iii
We want this probability:
And replacing we got:
