r-ruslan [8.4K]

Answer:

The probability of failure of trial 11 is $q = 0.16$

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

$q = 1 - 0.84$

=> $q = 0.16$

And from the attribute stated above the probability of failure of trial 11 is $q = 0.16$
