Example An oil corporation is competing for the rights to drill wells in field A and field B. It has a 40 percent chance of drilling a well in field A. If it does, the chances are that The probability of success is 45 percent. It has a 30 percent chance of drilling a well in field B. If it does, the well has a 55 percent chance of being successful. Calculate each of the following: Probabilities are as follows: a) Chances of drilling a successful well in field A, b) the likelihood of a successful well in field

2.12 Example
An oil corporation is competing for the rights to drill wells in field A and field B. It has a 40 percent chance of drilling a well in field A. If it does, the chances are that
The probability of success is 45 percent. It has a 30 percent chance of drilling a well in field B.
If it does, the well has a 55 percent chance of being successful. Calculate each of the following:
Probabilities are as follows:
a) Chances of drilling a successful well in field A,
b) the likelihood of a successful well in field B;
c) the likelihood of a successful well in field A as well as a successful well in field B,
d) the likelihood of at least one successful well in both fields, e) the likelihood of no successful well in field A,
f) the likelihood of no successful well in field B;
g) Chances of no successful well in both fields at the same time (calculate by two methods)
,
h) The likelihood of exactly one successful well in both fields.
Make a check with the probability you determined in part h.
