Answer:
Option (A)
Step-by-step explanation:
A set of real numbers is a combination of both rational and irrational numbers.
But the elements in the sets of rational and irrational numbers will be different.
In short, rational and irrational number sets are the two subsets of real numbers.
Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.
Option (A) is the correct option.

Answer:
so chance that their daughter is colorblind= 0%
Step-by-step explanation:
colorblindness is a sex-linked recessive trait,
let the alleles be XC- normal, Xc- colour-blind
the woman is heterozygous for this gene, so her genotype is XCXc
man is normal so his genotype is XCY
( man is XY and woman is XX)
XCY * XCXc
see table at the attachment corner below
probability of getting a colorblind progeny given that progeny is a girl= number of colorblind girl/total number of girls=0/2=0
so chance that their daughter is colorblind= 0%
