alleryStart learning →In n Bernoulli trials, P(x successes) is which term of the expansion of (q + p)^n?
Ax-th term
B(x - 1)th term
C(n - x)th term
D(x + 1)th term
Answer & Solution
Correct answer: D. (x + 1)th term
The expansion starts with the q^n term for zero successes, so x successes sit at the (x + 1)th term.
