The probability under the question is


    P = %2830%2A60%29%2F%2825%2A90+%2B+30%2A60+%2B+14%2A79+%2B+10%2A79%29.


The formula is self-explanatory.

If you need explanations - look into the formula, and it will tell you everything about itself.



Use your calculator to get the value, and round the answer as it is required.


By the way, from the post, it is unclear, in which form - percentage or decimal,- the answer must be presented, 
therefore I leave it to you.
