Answer:
0.79
Explanation:
Given a binomial experiment with 18 trials; and
[tex]P(\text{ success on trial 11\rparen}=0.79[/tex]By the conditions required for a binomial experiment, the probability of success (or failure) remains the same throughout the experiment and for each and every trial.
Therefore:
[tex]P(\text{ success on trial 15\rparen}=0.79[/tex]The answer is 0.79
