The distribution of the binomial random variable (x) has the following parameters: p = 0.3 and n = 9 Determine the P(X ≥ 2)

Sagot :

Answer:

Explanation:

The formula for calculating binomial probability is expressed as

P(x) = nCx * p^x * q^(n - x)

where

n is the number of trials

x is the number of successes

p is the probability of success

q is the probability of failure

From the information given,

n = 9

p = 0.3

q = 1 - p = 1 - 0.3 = 0.7

By using a binomial probability calculator,

P(x ≥ 2) = 0.804
