From the numbered cards numbered from 2 to 30, a card is drawn at random. find the probability of getting a card of square number or cube number.

Cards less than 14 : {2,3,4,5,6,7,8,9,10,11,12,13} 12 instances or P(N<14)=12/100=3/25
Perfect squares : {4,9,16,25,36,49,64,81,100} 9 instances or P(perf. sq.)=9/100
Prime number less than 20: {2,3,5,7,11,13,17,19} 8 instances or P(P<20)=8/100=2/25

I’m confused as to what you are asking 66 2/3 percentage wise
