One visitor of Yaya’s Thai, in San Antonio, Texas, was stumped by the puzzle he needed to solve to connect to theWi-Fi, so he decided to seek help from maths whizzes to crack the code and shared the equation on Reddit.
However, it is not just this Thai restaurant confusing visitors with math equations. CGTN reported a Chinese university came under scrutiny for requiring students to solve a calculus equation to access theWi-Fi.
Speaking to Beijing News, a member of PR staff said: “It aims at promoting the charm of higher mathematics and encouraging the freshmen to work hard.”
But why is this the case for the Thai restaurant? Well, it’s not entirely clear, but it was definitely a talking point.
One user tried to solve the password and said: “This looks a lot like a summation of a binomial probability density function. I strongly doubt the divider between N/m should even be there.
“It would then be equivalent to having a number of successes of at least half of the attempts made, statistically, with a success probability of 25 percent. The answer depends on the number of attempts though.
“Try password ‘binomial’ or ‘Binomial’ or something like that.”
Things got quite heated in the comments, with many users disagreeing with each other’s theories.
Meanwhile, some saw the funnier side with one user replying: “It’s “Password”.
Trying to make light of the situation, another user said: “The REAL answer to this problem is that they don’t even have Wi-Fi.”
If you really want to have your mind blown, read this response from user ‘Real_John_C_Reilly:
“The first term in the summation should be a combination not a fraction if this is a binomial distribution.
“In that case (N N/2) = N!/((N/2)!2), and, (N N) = 1. The first term in the summation expansion is (N N/2)* (3/16)N/2 and the last term is (1/4)N. I’d simplify the addition of the two terms: (1/4)N * [ N!/((N/2)!)2) * 3N/2 + 1]”
“I think this answer suffices if N/2 and N are consecutive. But if that were the case N=2 so the answer would be (7/16).
“Also this assumes a LOT, due mostly to how vague the q is, and is also primarily based off the original assumption the first term in the summation was a combination and not a fraction.
I’d try “sevensixteenths” as the password or “Binomial” and then demand more information because this q really ticked me off”
Is it really necessary to go to these lengths for aWi-Fi password?
The majority of responses think the password is ‘binomial CDF’ but with a typo, so now they just need to figure out where the typo is.
Seems like a lot of effort to most probably end up watching a random video or scrolling social media.
