The diagram shows the universal set U = {parallelograms}. Set A represents parallelograms with four congruent sides, while Set B
represents parallelograms with four congruent angles. How many of the parallelograms fall into the category A B?
2 answers:
Answer:
U ={ Parallelograms}
A= { Parallelogram with four congruent sides}={ Rhombus,Square}
B ={ Parallelograms with four congruent angles} ={ Rectangle, Square}
So, AB= { Square}
So among all the parallelograms "Square" is the only parallelogram which has all congruent sides as well as all congruent angles.

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
