Answer:


\boxed{(1)/(2) }

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 (1)/(10) +(4)/(10) =(5)/(10) =(1)/(2)

Answer:

1/2

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
