Suppose two dice (one red, one green) are rolled. Consider the following events. A: the red die shows 2; B: the numbers add to 5; C: at least one of the numbers is 2; and D: the numbers do not add to 9. Express the given event in symbols. HINT [See Example 5.] At least one of the numbers is 2, or the numbers add up to 5. C ∪ B

Step-by-step explanation:

Let the outcome from the two dice be (x,y) where x is the outcome from the red die and y is the outcome from the green die.

Event A: the red die shows 2

Event B: the numbers add to 5

Event C: at least one of the numbers is 2;

Event D: the numbers do not add to 9;

Therefore:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
