What’s the probability of getting a prime number and getting a vowel?

Ad libitum [116K]

First you need to know how many prime numbers are from 1 to 12.

Prime numbers: 2, 3, 5, 7, 11. There are 5 prime numbers.

The probability of getting a prime number would be 5/12.

Vowels from A to J would be A, E, I, so 3 vowels.

The probability of picking a vowel would be 3/10.

The probability of picking both would be 5/12 x 3/10 = 15 /120, which reduces to 1/8.

The answer is B.

Edward is driving a car on the highway. He drives for 28.5 miles in 3/8 of an hour. At this rate, how much distance can he cover

Rom4ik [11]

The distance covered in one hour is 76 miles.

Step-by-step explanation:

Edward drives a car for 28.5 miles.

Therefore, the distance he travels by the car = 28.5 miles.

The time it takes to drive 28.5 miles is 3/8 of an hour.

The formula to find the rate :

Rate = Distance traveled / Time taken in hours.

Here, the distance is 28.5 miles and time is 3/8 hour.

Rate = $28.5/ (3/8)$

To find the distance covered in 1 hour :

Let us assume, 'x' be the distance covered in one hour.

Rate = $x/1$

Now, comparing the rates to find the x value :

⇒ $28.5 / (3/8) = x /1$

⇒ $x = 28.5 \times 8/3$

⇒ $x = 228/3$

⇒ $x = 76$

Therefore, the distance covered in one hour is 76 miles.
