Easy -1.2 This is a straightforward application of the discrete uniform distribution variance formula Var(X) = (n²-1)/12 where n=16, requiring only direct substitution into a standard formula. While it's Further Maths content, the calculation itself is routine with no problem-solving or derivation required.
1 The random variable \(T\) follows a discrete uniform distribution and can take values \(1,2,3 , \ldots , 16\)
Find the variance of \(T\)
Circle your answer.
