Uur aim is to check whether 131 is a prime number or a composite number. Which among the following options is true? * None of these 131 is prime since it has no divisors from the set {2,3,5,7,11}. We need to check if 131 has a divisor from the set {2,3,5,7,11} and if one of them is not a divisor of 131, we can deduce that 131 is prime.

Question

Our aim is to check whether 131 is a prime
number or a composite number. Which among
the following options is true?
*
None of these
131 is prime since it has no divisors
from the set {2,3,5,7,11}.
We need to check if 131 has a divisor
from the set {2,3,5,7,11} and if one of
them is not a divisor of 131, we can
deduce that 131 is prime.

A small island country with less than 20,000 cars has decided to reissue the license plates for its cars and has decided on the following rules for assigning numbers and letters to the license plates. Each plate will have 7 character-positions that each must be filled. The leftmost character position will hold a letter from the set {D, E, H, G, X}. The next three positions will hold integers from the set {1, 9} but none of the integers can be repeated. The rightmost three positions must be entirely from the set {I, V, X} or entirely from the set {P, Q, R}, with repetition allowed in either case. For example, a valid plate would be G 127 XXI and an invalid plate would be G 337 PQX (two rules violated). What is the maximum number of different license plates following the rules?
