an experiment consists of picking at random a bit string of length ﬁve. Consider the following events:
E1: the bit string chosen begins with 1;
E2: the bit string chosen ends with 1;
E3: the bit string chosen has exactly three 1's.
-Find $p \left( E _ { 3 } \mid E _ { 2 } \right)$ .

The Answer of an experiment consists of picking at random a bit string of length ﬁve. Consider the following events:
E1: the bit string chosen begins with 1;
E2: the bit string chosen ends with 1;
E3: the bit string chosen has exactly three 1's.
-Find $p \left( E _ { 3 } \mid E _ { 2 } \right)$ .

An Experiment Consists of Picking at Random a Bit String p(E3∣E2)p \left( E _ { 3 } \mid E _ { 2 } \right)p(E3​∣E2​)
