Ten identical cards were marked, each with a different number from 0 to 9. The cards were turned face down and shuffled. Mary was asked to pick a card. Find the probability that she picked a number less than 4.

• 4/10
  Favourable cases are 0,1,2,3=4 and Total outcomes are 0,1,.....,9=10
  So probability of picking a number less than 4 = 4/10
