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

Mathematics

Ad libitum [116K]3 years ago
6 0

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.

Remark

It is not a straight line distance from the park to the mall. None of the answers give you that result. And if you know what displacement is, none of the answers are really displacement either. The distance is sort of a "as the crow flies." distance. There's a stop off in the middle of town.

Method

You need to use the Pythagorean Formula twice -- once from the park to the city Center and once from the city center to the mall.

Distance from the Park to the city center.

a = 3   [distance east]

b = 4  [distance south]

c = ??

c^2 = 3^2 + 4^2        Take the square root of both sides.

c = sqrt(3^2 + 4^2)

c = sqrt(9 + 16)          Add

c = sqrt(25)

c = 5

So the distance from the park to the city center is 5 miles

Distance from City center to the mall

a = 2 miles [distance east]

b = 2 miles [distance north]

c = ??

c^2 = a^2 + b^2   Substitute

c^2 = 2^2 + 2^2   Expand this.

c^2 = 4 + 4

c^2 = 8             Take the square root of both sides.

sqrt(c^2) = sqrt(8)

c = sqrt(8)          This is the result

c = 2.8

Answer

Total distance = 5 + 2.8 = 7.8
