Answer:
26.3 %
Explanation:
In the given question,
The probability of boys is given that is - 51.3%
Therefore the probability of girls will be = 100- 51.3
= 49.7%
The 51.3% probability of boys per thousand individual can be expressed as 513/1000= 0.513 P(B)
The 49.7% probability of girls per thousand individuals can be expressed as 497/1000= 0.497 P(G)
Now to calculate the probability that the first ans second child both are boys
We will fuse formula= P(B) x P(B)
= 0.513 x 0.513
= 0.263
Thus, 26.3 % is correct.
