And blanks 25

Now the possible number of outcomes = 15+25=40

Number of prizes /total outcomes

15/40=3/8

P(Np)=Np/(Np+Nb)
Np=No of prizes
Nb=No of blanks
On solving using above formula, we get 3/8 as ans.

Total Number Of Outcomes Possible n(s)= 15+25=40
Total Number of prize, n(E)= 15
Probability of getting prize P(E)= n(E)/n(s)= 15/40=3/8
