Helpp, pretty please;/

B

Step-by-step explanation:

The circumference of a circle is denoted by: C = , where d is the diameter.

Here, the diameter is d = 50. So, plug this in: C = ≈ 157

Thus, the answer is B.

Hope this helps!

Option D is correct.

That is,

Randomly generate an integer from 1 to 7 two times, and the probability is (1/7) ^2

Step-by-step explanation:

The probability of having birthday on a particular day of a week for anyone is 1/7. That is, 1 day out of the 7 days in a week.

Then for another person to have birthday on that same day is mathematically given as

(1/7) × (1/7) = (1/7)²

And this corresponds to option D. Therefore option D is the statement that best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday.

Hope this helps!
