Calculate the probability that Ade secures the job if the probability of at least one of them securing the job is 0.99.

Here are the solutions to your questions:

Question 13:
Let $P(J)$, $P(A)$, and $P(N)$ be the probabilities that John, Ade, and Ngozi secure the job, respectively.
Given:
$P(J) = 0.70$
$P(N) = 0.60$
Let $P(A) = p_A$.
The probabilities of not securing the job are:
$P(J^c) = 1 - 0.70 = 0.30$
$P(N^c) = 1 - 0.60 = 0.40$
$P
