Can someone help me with this statistics question?
A fair coin is thrown
Use a suitable approximation to estimate the probability of getting less than 115 Tails.

One option is using a normal approximation of the binomial distribution
P(n<115) = P(x<114.5 ) (due to quantization correction)
mean = np = 250*(1/2) = 125
standard deviation = sqrt( n (p) (1-p) ) = sqrt( 250*(1/2)*(1/2) )
standard deviation = sqrt( 62.5) = 7.90569415
P(x< 114.5) = P(z< ( 114.5-125) / (7.90569415 ) )
P(x<114.5) = P(z< -1.328156617 )
Looking up values
P(z< -1.33) = 0.09176
P(z< -1.32) = 0.09342
0.09176 + ( 0.09342-0.09176)*( -1.328156617 - (-1.33))/ 0.01
rounding to 5 digits of the table
P(n< 115) = approx. 0.09207

Police stop you at checkpoint to check if you’re chipped (aka vaccinated)
Police check the car; let's say 4 people car but signal only from 3; so, police stop it to chip the notyetchipped; signal from 4 now and police let the car go. This is prophecy by saint Vyacheslav Krasheninnikov. Notice police chip (aka vaccinate) people at gun point in Africa; so, no more "it's not gonna happen here" 'cuz it will soon enough, capisce?
Police do it on highways or when you leave your city... basically, you can't leave your city unless you're vaccinated; but vaccine = mark of the beast; so, escape now while your city doesn't have these rules; forgive me.
Gov't sprays chemtrails so that people feel symptoms of flu
5G will kill vaccinated; just read Georgia Guidestones' commandment of 500 million max population on earth; it fits with Orthodox Christian prophecy of 7 percent of people left
Russian Orthodox prophecy also says that there will be unbearable stench in winter. So, there you go. Russian winters are cold. So, they must have died from the new disease that doesn't have a name 'cuz it's caused by 5G.
martial law; Constitution was suspended; New World Order
read Book of Revelation; Chapters 13 and 14, please
chipped people will be influenced by super computers to receive World Passport (grey plastic card with no name on it), but when they stretch their hands to get it, gov't clerk presses secret button to administer the unforgivable green 666 tattoo by isotope rays
If you escape mark of the beast, then your direct ancestors go to permanent heaven
how to escape it? by hiding within a small group (10 - 15 people according to saints Gabriel Urgebadze and Seraphim of Sarov); no documents; no electronics
Project Pogo = Alex Jones, QAnon, Adam Green, etc. videos are put out so that gov't tracks who watches them. (Project Zyphr annihilates people who watch these videos). Drone with scopolamine will drill a hole in your window at 4 am. Once gassed, you will come out to the police van (waiting for you outside) yourself; you will be taken to underground camp to be tortured for adrenochrome. The rest of the people will be secretly (or even openly) chipped when they sign up for food in closed stores
AI (artificial intelligence aka demons) will post on your social media as if it were you doing it while you're on vacation; it will even make phone calls on behalf of you; no one will notice that you're missing in action.Source(s): According to the Last Prophet (aka incarnated ARCHANGEL URIEL aka saint healer VYACHESLAV KRASHENINNIKOV) if the last descendant rejects mark of the beast, then his/her direct ancestors go to permanent heaven. To reject mark of the beast, one needs to hide within a 10-15 people group without electronics/documents. Documents are from Satan; burn them. Electronics can be used to track you and to show the antichrist (even on old broken unplugged TV set from 1970's using Tesla’s ether); reject all vaccines, tests, temperature scans, etc.; forgive me.
