Question

If you are picking a number between 1-20 what is the probability that you will pick a multiple of two or a number greater than 15?

Answer 1

5/20 because they is 5 numbers between 15-20 that are larger than 15 

5/20 simplified is 1/4

I hope this helps

Answer 2

The probability of picking a multiple of two or a number greater than 15 is $\frac{3}{4}$

What is probability?

'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'

According to the given problem,

Multiples of two between numbers 1 to 20,

= { 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 }

Count of the multiples = 10

Total numbers = 20

Probability of picking a multiple of two = $\frac{10}{20}$

                                                                 = $\frac{1}{2}$

Numbers greater than 15 between 15 to 20,

= { 16, 17, 18, 19, 20 }

Count of the numbers greater than 15 = 5

Probability of picking a number greater than 15 = $\frac{5}{20}$

                                                                               = $\frac{1}{4}$

Probability of picking a multiple of two or a number greater than 15,

= $\frac{1}{2} + \frac{1}{4}$

= $\frac{3}{4}$

Hence, we can conclude, the probability is $\frac{3}{4}$
