Most people think babies are equally likely to come as either a boy or a girl. This is not true. Actually, about 51.3% of all babies are boys. If a family has two children (not twins), what is the chance that both children are boys

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.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
