Give the probability that the roll of a die will show 1 or 6

The probability of rolling a six-sided die and rolling a 1 or 6 is 1/3.

This is because, out of six options (1, 2, 3, 4, 5, and 6), 1 and 6 represent 2 of those 6, and 2/6 = 1/3

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
