Answer:
69%
Step-by-step explanation:
If Motor Works is selected, the probability that the worker is a female is 70%. If City Bank is selected, the probability is 68%.
But we don't know what company will be selected, we only know that they have the same probability, 50-50.
So, with 50% of probability the worker will be female with a 70% of probability (because they selected from Motor Works) and with 50% of probability the worker will be female with a 68% of probability (they selected from City Bank).
We express this as 50%*70% + 50%*68% = 69%
The multiplication means that both probabilities happen together and the sum means that happens one thing or the other (they select Motor Works or City Bank)
