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.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
