A password of a computer used five digits where they are from 0 and 9. What is the probability that the password solely consists of prime numbers and zero?
Choose one:
A) 1/32 B) 1/16 C) 1/8 D) 2/5 E) 1/2
We have five digits can be used for password -0,2,3,5,7.   1/32ssuming that the numbers can be repeated any number of times in the password, probability of selecting any one of them is 5/10 (out of 10 digits from 0-9)   So, 5/10 * 5/10 * 5/10 * 5/10 * 5/10 =1/32 (1/32)
