Example 34 Find the mean of the Binomial distribution B(4, 13) B(4, 13) means Here, n = 4, p = 13 So , q = 1 − 13 = 23 Hence, P (X = x) = 4Cx 𝟏𝟑𝒙 𝟐𝟑𝟒−𝒙 Mean of distribution = P (X = x) = 4Cx 13𝑥 234−𝑥 Mean = = 0 + 1 × 4C1 131 233+ 2 × 4C2 132 232 + 3 × 4C3 133 23 + 4 × 4C4 134 230 = 4 × 13 × 827 + 2 × 6 × 19 × 49 + 3 × 4 × 127 × 23 + 4 × 1 34 × 1 = 3281+ 4881+ 2481+ 481 = 10881 = 𝟒𝟑
