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

tangare [24]

Answer:

There are 72 cal in 2/3 cup serving of noodle soup

Step-by-step explanation:

The given parameters are;

The amount of calories in 3/4 cup serving of chicken noodle soup = 81 cal

The amount of calories in a 2/3 cup serving is given as follows;

3/4 cup contains 81 cal

1 cup contains 81/(3/4) cal = 81 × 4/3 cal = 108 cal

1 cup contains 108 cal

2/3 cup contains = 2/3 × 1 cup = 2/3 × 108 cal = 72 cal

2/3 cup contains 72 cal

Therefore, there are 72 cal in 2/3 cup serving of noodle soup.
