Answer:

c. She could either accept or not accept because now the probabilities of both doors are equal.

Step-by-step explanation:

After door B was opened, the probability that the prize is behind door A is 50% and behind C is also 50%, so, it doesn't matter which door she chooses.

Which number is prime?<br> 63 <br> 51 <br> 61 <br> 57
kondor19780726 [428]
Hey there!

No numbers go into a prime number other than one and that number. 9 and 7 go into 63, so it’s not 63. 3 and 17 go into 51, so it’s not 51. 19 and 3 go into 57, so it’s not 57. That leaves 61. Nothing goes into this other than one and 61, so the answer is 61.

I hope this helps!
