Here’s this week’s practice question– regular multiple choice, just one correct answer. We’ll be posting the answer and explanation tomorrow, good luck!

If points A and B are randomly placed on the circumference of a circle with radius 2, what is the probability that the length of chord AB is greater than 2?

Only 60 degrees at center covers chord less than radius. So 2*60=120 degrees on both side on a fixed radius. And rest 240 degrees will be meet the criteria.

probability that the length of chord AB is greater than 2 will be 240/360 or 2/3

it’s 2/3, as we have to deal in degree and properties of equilateral triangle …

120/360=1/3

Answer=2/3

It’s gotta be D. That was a tricky one

Answer choice is D. 2/3

Only 60 degrees at center covers chord less than radius.

So 2*60=120 degrees on both side on a fixed radius. And rest 240 degrees will be meet

the criteria.

probability that the length of chord AB is greater than 2 will be 240/360 or 2/3
