On a game show, Elena is given the choice of three doors: Behind one door is the Grand Prize; behind the others, consolation pri
zes. She picks Door A, and the host, who knows what is behind each door, opens Door B, revealing a consolation prize. The host then offers Elena the opportunity to change her selection to Door C. What should she do? A. She should not accept because the probability of Door A being the Grand Prize increased.
b. She should accept because the probability of Door C being the Grand Prize increased.
c. She could either accept or not accept because now the probabilities of both doors are equal.
d. She could either accept or not accept because the probabilities of the three doors were equal from the beginning.
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.
Okay so you would line them up then you would multiple 5 and 0 then 7 and 5 and then you add a 0 then you would get the answer 350 then you would multiply the same numbers then the answer you would get is 3500 then you add 3500+350=3850
