Answer:
1) yes ; 2) 1/36 ; 3) 1/36 ; 4) 1/18
Step-by-step explanation:
Given the following :
Two fair dice : 1 green ; 1 red
A) Are the outcomes on the dice independent:
Yes, becomes the outcome of the green dice does not have any effect on the outcome of the red dice.
B) Find P(1 on green die and 5 on red die).
Probability = (number of required outcome) / (total possible outcomes)
Total outcomes of a dice = 6
P(1 on green) = 1 / 6
P(5 on red) = 1/6
P(1 on green die and 5 on red die) :
(1/ 6) × (1/6) = 1/36
C) Find P(5 on green die and 1 on red die)
P(5 on green) = 1/6
P(1 on red) = 1/6
Find P(5 on green die and 1 on red die):
1/6 × 1/6 = 1/36
D) Find P((1 on green die and 5 on red die) or (5 on green die and 1 on red die))
P(5 on green die and 1 on red die) = 1/36
P(1 on green die and 5 on red die) = 1/36
P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) =
P(5 on green die and 1 on red die) + P(1 on green die and 5 on red die)
= (1/36 + 1/36) = 2 /36 = 1/18
