Answer:
a. 3/10
b. 7/10
Step-by-step explanation:
a. Total number of marbles = 10
Number of red marbles = 3
Probability = Number of outcomes/ Total number of outcomes
= 3/10
b. Total number of marbles = 10
Number of red marbles = 3
Number of marbles excluding the red marbles
= 10 - 3 = 7
Probability = Number of outcomes/ Total number of outcomes
= 7/10
The answer is The liquid must be in the cooler fewer than 10 minutes. This is because 3 × 10 is 30 and so it would lose 30° after 10 minutes, which makes it 60°, so if the liquid is in the cooler longer than 10 minutes then the temperature becomes less than 60°.
