Answer:
(a) 4/9
(b) 19/27
Step-by-step explanation:
The probability of each die turning up red or not turning red are:

(a). Exactly one face up is red.
The odds of only the first die being red are:

The same odds are valid for only the second or only the third die being red. Therefore, the probability that exactly one die turns up red is:

(b). At least one face up is red.
The probability that at least one die turns up red is the sum of the probabilities of exactly one (found in the previous item), two or all dice turning up red.
Following the same logic as in the previous item, the probability that exactly two dice turn up red is:

The probability that all die turn up red is:

Thus, the probability that at least one die turns up red is:

You would solve it just like how you would solve it with numbers.Solve it like how you would solve this 7=6*2.

Answer: The correct option is (A)
Option (A) is correct.
We have been given a diagram. We are asked find the measure of arc EAB.
First of all, we will find the measure of arcs ED and CB using our given information.
We know that measure of an inscribed angle is half the measure of intercepted arc.
We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.



Similarly, we will find the measure of arc DCB.











Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.
