Answer:
2/5
Step-by-step explanation:
So ,
Total no of multiples of three between zero to twenty are 6
and of 5 are 3
Since 15 is common total no of tickets we need to find probability for is 6+3-1=8
Total cards are 20
Probability = Outcomes we need/Total Outcomes
Therefore,
P(A card of multiple 3 or 5)=8/20 or
2/5
