Garrett throws a dart at a circular dartboard. the dartboard has a radius of 18 inches, and the bull’s eye in the center of the dartboard has a radius of 4 inches. what is the probability that a dart thrown at random within the dartboard will hit the bull’s eye? round your answer to the nearest tenth, if necessary. (1 point) 20.3% 4.9% 22.2% 4.5% you roll a standard, six-sided number cube. what is the probability of rolling a prime number or a number greater than 3? (1 point) 2/3 5/6 1 1/3

(1) B. 4.9%

(2) B.

Step-by-step explanation:

(1) We are told that Garrett throws a dart at a circular dartboard. The dartboard has a radius of 18 inches, and the bull’s eye in the center of the dartboard has a radius of 4 inches.

Let us find the area of dart board with radius of 18 inches as it will be total number of possible events.

Now let us find the area of bull's eye with radius of 4 inches as it will be number of favorable events.

Let us convert 0.049 to percent by multiplying 0.049 by 100.

Therefore, the probability that a dart thrown at random within the dartboard will hit the bull’s eye is 4.9% and option B is the correct choice.

(2) Let us find prime number from 1 to 6.

We can see that prime numbers between 1 and 6 are: 2, 3 and 5.

Number greater than 3 are : 4, 5 and 6.

We can see that 5 lies in both categories, so we will count 5 only once and our number of favorable outcomes will be 5.

Since we know that a dice has 6 sides so total number of possible outcomes will be 6.

Therefore, the probability of rolling a prime number or a number greater than 3 will be and option B is the correct choice.
