Each weekend during the summer, Kevin allocates his available time as follows: Working at the homeless shelter: 30% of his available time

Assisting at a children’s hospital fundraiser: 50% of his available time

Remaining available time is always spent providing support services for the elderly.

10% of his time at the homeless shelter, 20% of his time at the fundraiser, and 80% of his time with the elderly requires the use of his personal vehicle.

If you called Kevin while he’s donating his time to help others and found he won’t talk to you because he’s driving and doesn’t what to cause an auto accident, what is the probability you called when he’s busy providing support services for the elderly?
