We know that

[<span>cheese pizza, that does Rico have now]
=1-(1/3)-(1/7)
=(21-7-3)/21
=11/21

</span>[pepperoni pizza, that does Rico have now]
=3/7----> multiply by (3/3)------> 9/21

total pizza (pepperoni + cheese) that does Rico have now
=11/21+9/21------> 20/21----> 95.2% of one pizza

the answer is
20/21
