Question

If Ebe an event such that PIE
= 3/7. What is P(not E) equal to ?

If p is the probability of an event happening, then the probability that the event does not happen will be 1−p. ∴P(E)+P(Not E)=p+(1−p)=1.

Answer 2

Answer:

${\huge{\underline{\boxed{\red{Answer }}}}}$

P(E) = 3/7

P(not E) = 1 - 3/7 = 4/7
