$\frac{3}{5}$

P(odd)=$\frac{5}{10}$-there are 5 odd numbers out of 10 P(multiple of 3)=$\frac{3}{10}$ -three multiples of 3- P(odd or multiple of 3)=P(odd)+P(multiple of 3)+Probability events will occur P(odd or multiple of 3)-$\frac{5}{10}$ +$\frac{3}{10}$-$\frac{2}{10}$ P(odd or multiple of 3-$\frac{6}{10}$=$\frac{3}{5}$
