Answer:
d = 2.54951
Step-by-step explanation:
For:
(X1, Y1) = (4, 2)
(X2, Y2) = (4.5, 4.5)
d = \sqrt {(4.5 - 4)^2 + (4.5 - 2)^2}
When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).
You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.
Therefore:
P(sum is even) = 2 / 4 = 0.5
Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.
Y=2x+3 is a linear equation.
