Question

A survey was conducted in Canada to ascertain public opinion about a major national park region in the Banff-Bow Valley. One question asked the amount that respondents would be willing to contribute per year to protect the environment in the Banff-Bow Valley region. The following frequency distribution was found in an article by J. Ritchie et al. titled "Public Reactions to Policy Recommendations from the Banff-Bow Valley Study" (Journal of Sustainable Tourism, Vol. 10, No. 4, pp. 295-308).
Contribution ($) Frequency
0 .............. 85
1–50 ............ 116
51–100 ........... 59
101–200 ............ 29
201–300 ............ 5
301–500 ............ 7
501–1000 .......... 3
For a respondent selected at random, let
A = event that the respondent would be willing to contribute at least $101,
B = event that the respondent would not be willing to contribute more than $50,
C = event that the respondent would be willing to contribute between $1 and $200, and
