lukranit [14]
The equation for this would be: \frac{60}{165}=  \frac{x}{220}. first you want to multiply 60 by 220, then divide the product by 165.  60 times 220 is 13,200.  Now divide 13,200 by 165.  This will give you 80.  Todd has to eat 80 grams of protein each day to stay healthy.

malfutka [58]

Answer:

0.513 = 51.3% probability of being a female.

Step-by-step explanation:

We are given the following formula:

P(F \cup C) = P(F) + P(C) - P(F \cap C)

In which:

Event F: Female

Event C: Red-green color blindness.

Probability of a Female

We have to find P(F), which is given by:

P(F) = P(F \cup C) + P(F \cap C) - P(C)

We are given by:

P(C) = 0.039, P(F \cap C) = 0.004, P(F \cup C) = 0.548

So

P(F) = P(F \cup C) + P(F \cap C) - P(C) = 0.548 + 0.004 - 0.039 = 0.513

0.513 = 51.3% probability of being a female.
