    Just a Binomial prob question

    Ok so say p = 0.10 and there are 20 trials so n = 20

    using the nCx p^x q^n-x method (bernoulli trial) how would i work out the probabiltiy of x being less than 5

    so like, P(x < 5)

    thanks alot

    Caluclate Pr(X = 0) + Pr(X = 1) + Pr(X = 2) + Pr(X = 3) + Pr(X = 4).
