Answer:
The probability of failure of trial 11 is 
Step-by-step explanation:
Generally one the attributes of a binomial experiment is that the probability of success and failure is constant every trial so given from the question that the probability of success is 0.84 for trial 7 , then the probability of failure of trial 7 will be evaluated as

=> 
And from the attribute stated above the probability of failure of trial 11 is
