Question

9. Numbers 1 to 10 are written on ten separate slips, one number on each slip, kept in a box
and mixed very well. One slip is drawn, from the box without looking into it. What is the
probability of
a) getting a number 4.
b) getting an even number.
c) getting a 1-digit number.​

Answer 1

Step-by-step explanation:

a) Favourable event = 4.

   No. of favourable events = 1.

   Total outcomes = 10.

    Probability = 1/10

b) Favourable event = 2, 4, 6, 8, 10.

   No. of favourable events = 5.

   Total outcomes = 10.

    Probability = 5/10 = 1/2

c) Favourable event = 1, 2, 3, 4, 5, 6, 7, 8, 9.

   No. of favourable events = 9.

   Total outcomes = 10.

    Probability = 9/10
