1- 100 has 50 odd numbers and 50 even numbers.
Odd probability =50/ 100= 1/2.
(2)
Let k be a natural number, then a number divisible by 3 is represented as 3k.
1 & lt; 3k & lt 100
1/3 & lt; k & lt 100/3
∴ The maximum value of k =33, and the minimum value of k =2.
33-2+ 1=32
∴ 1- 100 There are 32 numbers divisible by 3.
Get the number divisible by 3 =32/ 100=8/25.
(3)
2-33 has an even number of 16.
Get an even number divisible by 3 = 16/ 100=4/25.
