How to solve Binomial Probability distribution problems?
The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability
The general formula of binomial probability distribution is;
P(X = x) = ⁿCₓ * pˣ * (1 - p)⁽ⁿ ⁻ ˣ⁾
where;
p is probability of success
n is number of trials or sample size
x is number of successful trials
Thus, If 6 human resource managers are randomly selected, the probability that at least 2 of them say job applicants should follow up within two weeks is;
P(X ≥ 2) = 1 - (P(0) + P(1))
P(0) = ⁶C₀ * 0.43⁰ * (1 - 0.43)⁽⁶ ⁻ ⁰⁾ = 0.0343
P(1) = ⁶C₁ * 0.43¹ * (1 - 0.43)⁽⁶ ⁻ ¹⁾ = 0.15524
P(X ≥ 2) = 1 - (0.0343 + 0.15524)
P(X ≥ 2) = 0.81047 = 81.047%
