Marks: +1, -0

If a random variable x assumes the values

\x _ { 1 } , \x _ { 2 } , \x _ { 3 } , \x _ { 4 }

with corresponding probabilities

\p _ { 1 } , \p _ { 2 } , \p _ { 3 } , \p _ { 4 }

then the expected Value of x is :

$\p _ { 1 } + \p _ { 2 } + \p _ { 3 } + \p _ { 4 }$
$\x _ { 1 } \p _ { 1 } + \x _ { 2 }\p _ { 2 } +\x _ { 3 } \p _ { 3 } + \x _ { 4 }\p _ { 4 }$
$\p _ { 1 } \x _ { 1 } + \p _ { 2 } \x _ { 2 } + \p _ { 3 } \x _ { 3 } + \p _ { 4 } \x _ { 4 }$
None of these
