Answer:
<u>The correct answer is 5/24 or 0.21</u>
Step-by-step explanation:
1. Let's review all the information given to answer the question correctly:
Science class in seventh grade = 4 girls and 4 boys
Science class in eighth grade = 5 girls and 7 boys
2. What is the probability that both students selected for the competition are girls, a seventh grader and an eighth grader?
These are independent events, therefore:
Probability of two independent events = Probability of A * Probability of B
Probability of both students selected for the competition are girls = 4/8 * 5/12
Probability of both students selected for the competition are girls = 20/96 = 5/24
<u>The correct answer is 5/24 or 0.21</u>
Answer:
The greatest amount of fizzy drink he can make is 420 ml
Step-by-step explanation:
we know that
The ratio of the parts of orange juice to parts of lemonade is
so
using proportion
Find out the milliliters of lemonade needed to make fizzy drink with 300 ml of orange juice
Let
x -----> milliliters of lemonade needed
<em>Find the greatest amount of fizzy drink he can make</em>
Adds the milliliters of lemonade plus the milliliters of orange juice
therefore
The greatest amount of fizzy drink he can make is 420 ml
