    Which is 50. So (60/100) x (50/100)

    Yes! And your result is 30%. I don't think it was very clear but did you understand a little bit?

    probability = favorable cases / possible cases = 60/100 × 50/100 = (60 × 50)/(100×100) =3000/10000 = 0.3 = 30

    As 30% that's your total. Because it's 50% and 60%
