During their phone call, Ameena realises that she also needs something for the winter. So she comes down to the store, where Deepika is waiting for her, and plans to pick an item exactly the same way, by choosing randomly among the available options. The two friends wear the same size, and they decide to make their random choices in their minds at the same time, but independently, without each person knowing what the other is deciding. Calculate the probability that they both pick the same type of item, regardless of colour.
