Question

Five bikers join a race. In how many possible ways can they be arranged as

first, second and third placers?
1. How many positions to be filled?​

Answer 1

60 different possibilities

Explanation:

Number of bikers = 5

Positions = first, second and third

First positions = all 5 riders can take the first spot = 5 possibilities

Second spot = position 1 has been filled hence number of possibilities = ( 5 - 1) = 4

Third spot = position 1 and 2 has been filled ; number of possibilities =. (5 - 2). = 3

Number of possible arrangements :

5 * 4 * 3 = 60 different possibilities
