Suppose two dice (one red, one green) are rolled. Consider the following events. A: the red die shows 1; B: the numbers add to 6; C: at least one of the numbers is 3; and D: the numbers do not add to 11. Express the given event in symbolic form.
Either the numbers add to 11 or the red die shows a 1.
D ∩ B
D ∩ A
D' ∪ A
D' ∩ A
D' ∪ B

How many elements does it contain?

(a)(C)

(b)8 elements

Step-by-step explanation:

Ina toss of a red and green dice, given the events:

=The numbers do add up to 11.

Therefore, the event: Either the numbers add to 11 or the red die shows a 1 is written as:

(b)

Sample Space of A={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)}

Sample Space of ={(5,6),(6,5)}

={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(5,6),(6,5)}

contains 8 elements

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

b is the right answer
