Answer:
1/18
Step-by-step explanation:
The dices are
1,1 1,2 1,3 1,4 1,5 1,6
2,1 2,2 2,3 2,4 2,5 2,6
3,1 3,2 3,3 3,4 3,5 3,6
Value greater than 8= 2
Total= 36
P( Value greater than 8)=2/36
= 1/18
Answer:
\frac{17}{24}
Step-by-step explanation:
Given that Box 1 contains 2 red balls and 1 blue ball. Box 2 contains 3 blue balls and 1 red ball. A coin is tossed. If it falls heads up, box 1 is selected and a ball is drawn. If it falls tails up, box 2 is selected and a ball is drawn.
P(selecting Box 1) = 0.5 = P(selecting II box) (assuming a fair coin is tossed)
P(Red/Box I ) =
P(Red/Box II) =
Box 1 and Box 2 are mutually exclusive and exhaustive events.
So probability of selecting a red ball.
= probability of selecting a red ball from box 1 + probability of selecting a red ball frm box 2
