QUESTION 1- Two balanced 4 sided-dice, each with faces labeled by 1, 2, 3 and4. if Ali plays a game where he tosses two balanced 4 sided-dice He wins 3 points if the sum is 6. He wins 2 points if the sum is greater than 6. He loses 1 point if the sum is less than 6. Find the probability distribution sum. 2- A dice is loaded in such away that each odd number is twice as likely to occur as each even number. find P(G) , where G is the event that a number greater than 3 occurs on a single roll of dice.

Kindly check explanation

Explanation:

Given that:

Two Four-sided dice numbered : 1, 2, 3, 4

Sample space = 4² = 16

3 points wonif sum = 6

2 points won If sum > 6

1 point lost if sum < 6

SAMPLE SPACE

___ 1 2 3 ___4

1 __2345

2__3456

3__4567

4__5678

Probability = (number of required outcomes / total possible outcomes)

P(6) = 3 / 16 = 0.1875

P(>6) = 3 / 16 = 0.1875

P(<6) = 10 / 16 = 0.625

X32 - 1

P(X)0.18750.18750.625__

XP(X)0.56250.375 - 0.625__

Sum of the distribution :

0.1875 + 0.1875 + 0.625 = 1

Σ XP(X) = (0.5625 + 0.375 + (-0.625))

Σ XP(X) = 0.5625 + 0.375 - 0.625

Σ XP(X) = 0.3125

2.) A dice is loaded in such away that each odd number is twice as likely to occur as each even number. find P(G) , where G is the event that a number greater than 3 occurs on a single roll of dice.

Since each odd number is twice as likely to occur as each even number

Odd numbers on a dice = 1, 3, 5

Hence, sample space = {1, 1, 2, 3, 3, 4, 5, 5, 6}

find P(G) , where G is the event that a number greater than 3 occurs on a single roll of dice.

Required outcomes = numbers greater than 3 =(4, 5, 5, 6)

P(G) = (number of required outcome / Total possible outcomes)

P(G) = 4 / 9

the histogram that represents the data with the largest spread is data set b

answer: the mildest forms of push polling are designed merely to remind voters of a particular issue. for instance, a push poll might ask respondents to rank candidates based on their support of an issue in order to get voters thinking about that issue. many push polls are negative attacks on other candidates.
