The probability that a black and then a blue marble were chosen is 1/16 if the total number of marbles is 16
<h3>What is probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Here data is not given so we are assuming:
Total number of marbles = 6(green) + 2(blue) + 8(black) = 16 marbles
Probability of getting black = 8/16 = 1/2
Probability of getting blue = 2/16 = 1/8
From the product rule:
Probability that a black and then a blue marble = (1/2)(1/8) = 1/16
Thus, the probability that a black and then a blue marble were chosen is 1/16 if the total number of marbles is 16

Answer: the correct answer is choice A
Step-by-step explanation:
This is because the inequality symbols are pointed the correct way. The symbols are also showing the correct answers with the greater than or equal to sign is on the correct point value. You find the place for the equal to or greater/less than symbol by the open or closed circle point. An open circle means the number is not included in the answer while a closed circle is included in the answer.
Answer:
Step-by-step explanation:
Use the distribution property and multiply 7 to x and -4 to get
7x-28 = 84
then add 28 to both side
7x= 112
then divide 7 to both side to get
x= 16
