Question

P(not E) = 7/9, then P(E) will be: ​

Answer 1

Answer:

2/9

Step-by-step explanation:

Answer 2

$\underline {\pink { Complementary \:event } }$

The event which is against to occuring to 'E' is called as complementary event (' not E ' ).

$The \:sum \:of \: probability \: of \: occuring \\'E' \: and \: probability \: of \:not \: occuring ' E' = 1$

$\boxed { \blue { P(E) + P( not \:E ) = 1 }}$

$Here , P(not \:E ) = \frac{7}{9} , \:\red{P(E) = ?}$

$\red{ P(E) } + \frac{7}{9} = 1$

$\implies \red{ P(E) } = 1 - \frac{7}{9}$

$\implies \red{ P(E) } = \frac{9-7}{9}$

$\implies \red{ P(E) } = \frac{2}{9}$

Therefore.,

$\red{ P(E) } \green{ = \frac{2}{9} }$
