Question

A number is chosen at random from 1 to 10. Find

Answer 1

Answer:

$\boxed{\frac{1}{2} }$

Step-by-step explanation:

There are total 10 outcomes.

$1,2,3,4,5,6,7,8,9,10$

The probability of selecting 4 is 1 outcome out of total 10 outcomes.

Factors of 6 are $1,2,3,6$.

These are 4 outcomes out of total 10 outcomes.

The probability of selecting 4 or a factor of 6 is:

$\displaystyle \frac{1}{10} +\frac{4}{10} =\frac{5}{10} =\frac{1}{2}$

Answer 2

Answer:

1/2

Step-by-step explanation:

The possible outcomes are

1,2,3,4,5,6,7,8,9,10

Factors of 6 are 1,2,3,6

or a 4

1,2,3,4,6 are the outcomes we want

There are 5 "good" outcomes

P( 4 or a factor of 6) = "good" outcomes/ total

                                  = 5/10

                                   =1/2
