Answer:

26/35

Step-by-step explanation:

If the events are mutually exclusive, all you have to do for P(S or T) is do P(S)+P(T).

So we are doing 1/7 + 0.6.

I prefer the answer as a fraction so I'm going to rewrite 0.6 as 6/10=3/5.

So we are going to add 1/7 and 3/5.

We need a common denominator which is 35.

Multiply first fraction by 5/5 and second fraction by 7/7.

We have 5/35+21/35.

This gives us 26/35.
