A company follows a model of bifurcating the tasks into the categories shown below.

At the beginning of a financial year, it was noticed that:
♦ `40%` of the total tasks were urgent and the rest were not.
♦ half of the urgent tasks were important, and
♦ `30%` of the tasks that were not urgent,were not important
What is the probability that a randomly selected task that is not important is urgent? Use Bayes' theorem and show yoursteps.
