• 17
• 26
• 35
• 44
• 53
• 62
• 71
• 80

Answer 2

Answer:

$\frac{8}{90} or \frac{4}{45}$

Step-by-step explanation:

there are 90 two digit numbers. From 10 to 99. to get it 99-9=90 and that is your sample space. Among all those numbers there are 8 nunbers whose sum of its digits is 8. They are: 17,26,35,44,53,62,71,80. So, 8/90 is the probability or 4/45 in lowest term
