Question

A computer randomly selects a number from the given set.

{1, 2, 5, 10, 25, 30, 36}

What is the probability that an even number is selected?

Enter your answer as a fraction, in simplest form, in the box.

Answer 1

even numbers are 2, 10, 30 and 36, so there is 4 even numbers in set of seven and probability that an even number is selected is 4/7

Answer 2

Answer:
`(4)/(7)`

Explanation:

The given set : {1, 2, 5, 10, 25, 30, 36}

Total numbers in the set = 7

Even Numbers = {2,10,30,36}

The number of even numbers in the set=4

Now, the probability that an even number is selected is given by :-

`\text{P(Even)}=\frac{\text{Even numbers}}{\text{Total numbers}}\\\\\Rightarrow\text{P(Even)}=(4)/(7)`
