Question

If P(E)=0.2,then the value of P(not E) is​

Answer 1

ANSWER✓

$&#10154$ P(E) = 0.2

$&#10154$ We know that the sum of probability of P(E) and P(not E) = 1

$\implies \: \: P(E) + P(not \: E) = 1 \\ \\ \implies \: \: 0.2 + P(not \: E) = 1 \: \: \: \: \\ \\ \implies \: \: P(not \: E) = 1 - 0.2 \: \: \: \\ \\ \implies \: \: P(not \: E) = 0.8 \: \: \: \: \: \: \: \: \: \: \:$
