Problem #7: If a die is rolled one time, find the probability of getting a 5 or an even number.

1 answer:

4 0

Getting a 5 is a 1/6 probability if your using a 6 eyed dice. It’s 1/2 chance you’ll roll an even. Original answer is 3/6 for even but you probably have to simplify equaling 1/2

Fifteen times the square of a non-zero number is equal to 20 times number.What is the number? Its not 4/3

e-lub [12.9K]

The number is (2√3) / 3

To find the missing number, convert what it says in words to an equation:
$15 {x}^{2} = 20x$
Divide both sides by 15:
${x}^{2} = \frac{20}{15} \\ \\ {x}^{2} = \frac{4}{3}$
Take the square root:
$x = \sqrt{ \frac{4}{3} } \\ \\ x = \frac{2}{ \sqrt{3} } \\ \\ x = \frac{2 \sqrt{3} }{3}$
