aleksklad [387]
The answer is A.5/8.

Why?

Multiply 1/4 with 2/2 to get the same denominator as 7/8, 8. That will yield 2/8.Then, simply subtract 2/8 from 7/8 (7/8 - 2/8), and that equals 5/8.

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
