Answer:
Picking an even number is an as likely event and it's probability is 1/2
Step-by-step explanation:
We know that the numbers present are 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16
The odd numbers are 1,3,5,7,9,11,13,15
The even numbers are 2,4,6,8,10,12,14,16
There are 8 even numbers and 8 odd numbers.
And also if we pick a number it should be either an even number or an odd number.
Probability(Getting an even number) =
Probability = = 1/2
Therefore picking an even number is an as likely event and it's probability is 1/2
