Answer:
a.
b.
Step-by-step explanation:
We are given that a die is rolled
Let x bet the cases in favor of 5.
Number of cases in favor of 6=x
Then according to question
Number of cases in favor of 1=3x
Number of cases in favor of 2=3x
Number of cases in favor of 3=3x
Number of cases in favor of 4=3x
Sum of total cases=
Probability of getting 5 =
Probability of getting 1=
1.We have to find probability should be assigned to rolling a 4.
The probability of getting =
2.We have to find the probability of rolling 6.
The probability of getting 6=
