Answer 3

how do I explain whether it is false or true?

Answer 4

All you have to say is that "it follows from the definition of Pascal's triangle that its fifth row sums up to 32." :P

Answer 5

for n trials, the sum of the terms is \[2^{n}\]

Answer 6

thanks everyone!

Answer 7

it could be easily proven....the different terms in the pascals triangle for 'n' trials are the coefficients of x^0,x^1 and so on in the expansion of
\[(1+x)^{n}\]
and to eliminate all terms of x and get the coefficients(as sum) just put x=1...
which obviously mean \[2^{n}\]
