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.
