Question

A string orchestra has 10 members
who play violin, 3 who play viola,
5 who play cello and 2 who play
double bass. There are 14 members
who are right-handed. If a member
of this string orchestra is chosen at
random, what is the probability that
he or she is:
(a) right-handed and plays the
cello?
(b) left-handed and doesn’t play
the violin?
Could you draw me a diagram about how to approach the problem. eg tree diagram, table, etc. Thank you.
