Step 1
Let X be a random variable follows binomial distribution with sample size n and probability of success p.
XB(n,p)
Step 2
For calculating probability of at least 8 successes the expression is as follow:
P(X8)=P(8)+P(9)+P(10)+
Thus, in a binomial probability question, the phrase “at least 8” consists of {8, 9, 10, …}.
Hence, the last option is correct.
