Answer:
(a) Option A. independent
(b) 
Step-by-step explanation:
Two events A and B are considered dependent if the occurrence of one affects the probability of occurrence of another.
In this case, the events are independent because the birth of a girl or a boy does not affect the probability of obtaining a 1 by throwing a 16-sided die.
In the same way, throwing a die and obtaining the number 1 does not affect the probability that a baby is a girl or a boy.
When two events are independent then
The probability that a baby is a girl is
The probability of obtaining a 1 when casting a 16-sided die is:
Then:
Answer:
575in³
Step-by-step explanation:
Volume for a Sphere = 4/3πr³
Radius = 13/2 = 6.5
4/3(3.14)(6.5³) = 1149.763333
Because it's half a sphere, just divide by 2
1149.763333/2 = 574.881667
Rounded to the nearest cubic inch = 575
Let x be the amount of the solution containing 10% of the chemical. Then, the solution with 40% chemical becomes 10 - x. The equation for balancing the chemical content of the solution is,
0.10x + 0.40(10 - x) = 0.25(10)
The value of x is 5. Hence, the druggist should mix 5 ounces of each. There are 2.5 ounces of chemical in the final mixture.
