Question

Suppose the probability of an event occurring is P(A) , and the probability of the event not occurring is P(A'). If P(A)=m and P(A') = n which of the following equations NEED HELP

Answer 1

$Given \: The \: probability \:of \:an \:event \\occurring = P(A)$

$and \: probability \:of \:an \:event \: not \\occurring = P(A')$

$P(A) = m, \:and \: P(A') = n$

$\pink { P(A) + P(A') = 1 }$

$\implies m + n = 1$

Therefore.,

$\red { Required \: Equation : }$

$\green { m + n = 1 }$
