Step-by-step explanation
Probability of an event is calculated as the number of elements in the event divided by the total number of elements
Question 3
We have been told that the temperature was over 80 degrees for 25% of the days.
So, the likelihood or probability of having a temperature over 80 degrees = 25% = 0.25
That is, ¼.
Question 4
It is said that you (or a random student) completes the assignment on 25 out of 25 days.
The likelihood or probability of completing the assignment will now be calculated as
Number of times that the student completes the assignment = 25
Total number of times assignments were given = 25
Probability or likelihood of completing the assignment = (25/25) = 1
Question 5
Roll a 6-side die, we need the probability of getting a 2
Number of sides marked 2 on a 6-side die = 1
Total number of sides on a 6-side die = 6
Probability of rolling a 2 = (1/6)
Question 6
Roll a 6-side die, we need the probability of getting an odd number.
Number of sides with odd number on a 6-side die = n {1, 3, 5} = 3
Total number of sides on a 6-side die = 6
Probability of rolling an odd number = (3/6) = (1/2)
Question 7
Roll a 6-side die, we need the probability of getting a 4
Number of sides marked 4 on a 6-side die = 1
Total number of sides on a 6-side die = 6
Probability of rolling a 4 = (1/6)
Question 8
Roll a 6-side die, we need the probability of getting a number greater than 6
Number of sides greater than 6 on a 6-side die = 0
Total number of sides on a 6-side die = 6
Probability of rolling a number greater than 6 = (0/6) = 0
Hope this Helps!!!
