I believe it would be a dental student.
X^2 + y^2 can be replaced by r^2 to obtain the polar equation equivalent to x^2 + y^2 = 5. Thus, r^2 = 5, and r = sqrt(5). That's all that's necessary. No matter what the angle is, r will always be sqrt(5).
Answer:

Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Mathematically, this is

In this problem, we have that:
Desired outcomes:
There are 52 cards, of which 13 are diamonds.
We want non diamond cards, so 
Total outcomes:
Deck of 52 cards, so 
Probability

You can round 790 to 800, and 9 to 10. So then it become 800/10, or 80. Your answer would be around 80. Hope I helped!
