Question

1. Classify the following sets into empty set, finite set and infinite set. In (non-empty) finite sets, mention the cardinal number. (1) (all colours of a rainbow] (ii) |x| * x is a prime number between 7 and 11) (iii) (multiples of 51 (iv) (all straight lines drawn in a plane) (v) \ x|x is a digit in the numeral 550131527) (vi) \ x|x is a letter in word SUFFICIENT] (vi)|x|x=4n,n in I and x < 10!​

Answer 1

Answer:

Step-by-step explanation:

1)  cardinal number: 7 , finite  set

ii) null set ∅

there is no  prime numbers  between 7 and 11

iii) cardinal number = 1

because there is only one multiple of 51 that is 51 table only

and it an finite set

iv) infinite set
