Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 3.
1 answer:
Answer:
1 / 36
Step-by-step explanation:
A roll of 2 fair dice :
Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36
Probability = required outcome / Total possible outcomes
Required outcome = total less than 3 = 1 (from sample space provided)
Hence,
P(total less than 3) = 1/36

About 1.75 million people live in a circular region with a 15-mile diameter. Find the population density in people per square mile.
Solution: We are given that the population of a circular region = 1.75 million =
Also we are given the circular region has a diameter = 15 mile
Which means the radius of region mile
Therefore, the area of the circular region
Now the population density per square mile is:
Therefore, the population density per square mile is 6086
