When dragons on planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 39% of the eggs are yellow, and the rest green. Next spring the lead scientist has permission to randomly select 66 of the dragon eggs to incubate. Consider all the possible samples of 66 dragon eggs. What is the usual number of yellow eggs in samples of 66 eggs

The usual number of yellow eggs in the selected sample is 26.

Step-by-step explanation:

It is given that there are 2 types of dragon eggs: Yellow and green

Observation says that 39% of the eggs are yellow.

When selected at random for incubation:

Number of eggs selected are = 66

To evaluate the number of yellow eggs, we must calculate 39% of 66 eggs

Hence, the usual number of yellow eggs in the selected sample is 26.

B = A over 3 so put the three under the a and -c . a =3 (B+C) divide both sides by 3. A over 3 a equals B plus c subtract C from both sides. B = A over 3 - C I hope this helps so B = (A/3) - C remember divide both sides by 3 subtract C from both sides
