Question

The given spinner is spun twice and the two numbers got are used to form a 2 digit number. How many different 2 digits numbers are possible?

Answer 1

On the first spin we get any of the five numbers to form one’s place then in the second spin the number got will fill 10’s place.

∴ Number of ways = 5 × 5 = 25 ways.

Removing the repetitions (11, 22, 33, 44, 55) once we get 25 – 5 = 20 ways.

20 different two-digit numbers are possible
