Question

Aidan writes numbers on his ten fingers as 5, 7, 9, 11, 13, 15, 16, 19, 22, 23. What is the probability of picking an even numbered finger ?

Answer 1

22 is the olny even number and 1/10 that's only a 10% chance

Answer 2

It would be 2/10, or 1/5, since two out of the 10 numbers are even. 2/10 simplifies to 1/5, since there is 1 for every 5 numbers.

We could turn this into a percentage by dividing 1 by 5, which gives us 0.2. Then we can multiply by 100 to get 20.

So, our probability of choosing an even number is:
2/10
OR
1/5
OR
20%

Hope I could help!
