The total number = 4 (1,2,3,4)
number of prime numbers= 2 (2,3)
number divisible by 32 = 3, (1,2,4)
[tex]\text{Prb(prime numbes)}=\frac{2}{4}=\frac{1}{2}[/tex][tex]\text{prb(number divisible by 32)=}\frac{3}{4}[/tex]
Hence the probability of picking a prime number and then a number divisible by 32 is
[tex]\frac{1}{2}\times\frac{3}{4}=\frac{3}{8}[/tex]
In percentage we have,
[tex]\frac{3}{8}\times100=\frac{75}{2}[/tex]
37.5%
Hence the probability in percentage is 37.5
