The simplest case of a normal distribution is known as the standard normal distribution. This is a special case where Î¼=0 and Ï=1, and it is described by this probability density function : The factor in this expression ensures that the total area under the curve is equal to one.n probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.
That gives considerable scope for speculation over what is meant by this phrase. The most common interpretation of 'break' in this context is 'to deviate from a straight line', as in the cricketing term 'off break', to unstraighten the leg by bending at the knee, by bowing or curtsying. 'Break a leg' also means 'make a strenuous effort'.
The shepherd would break the wandering sheep's leg, and then that would require the shepherd to carry the sheep around on his shoulders afterwards for an extended period of time.irst, no sheep would intentionally, repeatedly walk away from the flock. Sometimes a lamb might get separated because the flock has moved away and it can't keep up, but crippling it isn't going to fix that. Second, a sheep with a broken leg is going to require enough care that the rest of the herd will be neglected.
