PLEASE ANSWER picture shown

Alexxx [7]

$\frac{x}{2} + \frac{7}{9x}$
$= \frac{x*9x}{2*9x} + \frac{7*2}{9x*2}$
$= \frac{9x^2}{18x} + \frac{14}{18x}$
$= \frac{9x^2+14}{18x}$

Therefore the answer is B.

Hope this helps !

The true probability of a baby being a girl is 0.475. What is the probability that at least one is a boy?

alex41 [277]

Answer:

The probability that at least one is a boy is 0.525

Step-by-step explanation:

P(Baby being a girl) = 0.475

Now, if A is any arbitrary event . Then:

as we know P(A)+ P(not A) = 1

⇒ P(A not happening) = 1 - P(A event happening)

Also, P( baby not being a girl) = P(baby being a boy)

So, P(baby being a boy) = 1 - P( baby being a girl)

= 1 - 0.475 = 0.525

Hence, the probability that at least one is a boy is 0.525
