So there are a total of 10 cards.....And you want either a number > 5   or an odd number

there are 5 numbers > 5 (6,7,8,9,10)
and there are 5 numbers that are odd (1,3,5,7,9)

you want the probability of choosing either or....so

5 are > 5    3 more are odd so

You have 8 possibilities that you want

$$\frac{ 8 }{ 10 }$$

simplify this down to get

$$\frac{ 4 }{ 5 }$$

Total number of cards? 10
Cards with number greater than 5? 6, 7, 8, 9, 10, or 5 cards with desired outcomes.
Cards with odd numbers? 1, 3, 5, 7, 9, of which 1, 3, and 5 are not included in numbers greater than 5. So this adds 3 more desired oucomes.
Total number of desired outcomes: 8
Probability = desired outcomes/total outcomes = 8/10 = 4/5
