For a binomial random variable the probability of success per trial is  π = 0.35

 

28 What is the probability of 10 or fewer (at most 10) successes in 30 trials?
a 0.5179            
b 0.5078            
c 0.4978            
d 0.4880            
Expert Solution
Step 1

Given that 

p=probability of success per trial=π=0.35

n=30 , p=0.35 , q=1-p=1-0.35=0.65

X~Binomial(n=30 , p=0.35)

Find P(X≤10)
