First we find the sum of all values using the mean formula.
Then we subtract the value 70 from the total sum to get the sum of the values without 70 (in order to compute the mean of these values)
Then we compute the mean.
If you have any additional questions ask.

Pascal's triangle is a visual representation of the coefficients involved in a binomial expansion. The 
th row of the triangle gives the coefficients of the terms in the expansion of 
.
The triangle itself looks like
and so on, while the expansions for
are
and so on.
The binomial theorem says that
The numbers in theth row of the triangle are just 
, with 
.
So no, the binomial theorem and Pascal's triangle are not the same thing. Pascal's triangle is a way of organizing the pattern exhibited by the result of the binomial theorem.
