Answer:

The required probability is \simeq 0.26214

Step-by-step explanation:

There were 4,065,014  births in a given year and of those births 2,081,287 were boys and 1.983,727  were girls.

So, P(both children will be boys) = \frac {^{2081287}{C}_2}{^{4065014}{C}_{2}}

\simeq 0.26214

noname [10]

Answer:  log_39=2 is the logarithmic equation which is equivalent to3^2=9.


Step-by-step explanation:

According to the laws of logarithms

log_b\ x=n ,where b=base ,n,x all are positive

It can be written in exponential form such as

x=b^n

Now in the given question x=9 ,b=3 and n=2 such that it will equals to
