The probability that a vehicle will change lanes while making a turn is 55%. Suppose a random sample of 7 vehicles are observed making turns at a busy intersection. a) Find the probability that no more than 4 vehicles will change lanes while making the turn. b) Calculate the expected value u of the vehicles that will change lanes while making turn c) Calculate the standard deviation

Suppose outside temperature is 55◦F, while the temperature
inside a building is 72◦F. The building is heated but not air
conditioned, so the partial pressure of water vapor is the same
both inside and outside the building. Finally, suppose the dew
point outside is 40◦F. What is the dew point inside? What are the
relative humidities inside and outside the building? (We are most
comfortable if relative humidity is between 30% and 50%. This
question shows why air in heated...

(a) You decided to turn a neutron into a proton. Making sure
that the charge is conserved, you wrote down n → p + e-.
When you actually did the experiment, an antineutrino came out in
addition, making the actual interaction n → p + e -+ ¯ν.
Among what needs to be conserved, what was not conserved in the
interaction without the antineutrino?
(b) You managed to capture the emitted electron inside of a
one-dimensional infinite potential well with...
