TypeName the distribution

  1. The discrete random variable \(X\) has probability distribution
$$\mathrm { P } ( X = x ) = \frac { 1 } { 10 } \quad x = 1,2,3 , \ldots 10$$
  1. Write down the name given to this distribution.
  2. Write down the value of
    1. \(\mathrm { P } ( X = 10 )\)
    2. \(\mathrm { P } ( X < 10 )\) The continuous random variable \(Y\) has the normal distribution \(\mathrm { N } \left( 10,2 ^ { 2 } \right)\)
  3. Write down the value of
    1. \(\mathrm { P } ( Y = 10 )\)
    2. \(\mathrm { P } ( Y < 10 )\)
