Answer:
(a) 0.1666 (b) 0.5 (c) 0.166
Step-by-step explanation:
A die is rolled so sample space = { 1,2,3,4,5,6 } so n=6
(a) the number showing is four so expected value is only 4 so favorable outcomes {4}
so probability
(b) the number showing an even number
so favorable outcomes= { 2,4 ,6 }
so probability
(c) the number showing greater than 5 that is only {6}
so probability
Answer:
{(-34/7, -16/7)}
Step-by-step explanation:
Rearrange values, multiply to solve for x.
(5) 2y = 3x + 10
(-2) 5y = 4x + 8
Solve for x.
10y = 15x + 50 ↓
-10y = -8x -16
Combine and evaluate.
0 = 7x + 34
Subtract 34 from both sides.
7x = -34
Divide both sides by 7.
x =
Plugin x value into either equation to solve for y.
2y = (3 × ) + 10
2y = + 10
2y =
y =
