We need to find that the probability that the person is male or frequently involved in charity work.
From the attached figure,
Total no of people = 2881
No of Males = 1479No of females who are frequently involved = 205 ∴ Total no. of males or frequently involved = Sum of both
= 1479 + 205
= 1684∴ Probability =

=

∴ Probability = 58.45%
