52. Numbers 1 to 10 are written on ten separate slips (one number on one slip), kept in a box and mixed well. One slip is chosen from the box without looking into it. What is the probability of getting a number greater than 6?

Since, there are 10 slips. At a time any slip can be taken out.
∴ Number of total outcomes = 10
Now,

∴ Favourable outcomes = 4
Thus, probability of getting a number less than six =

space space space 4 over 10 equals 2 over 5.
