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
