Explanation / Answer

Solution :

From given table ,

The probability that the person is frequently or accasionally in charity work is ,

P(being frequently involved or being occasionally involved)

= P(frequently) + P(Occasionally) - P(frequently and occasionally)

= (427/2851) + (884/2851) - 0

= (427 + 884) / 2851

= 1311 / 2851

= 0.460

P(being frequently involved or being occasionally involved) = 0.460
