What is the probability that event E or event F or both will occur?
(1) The probability that event E will occur is 0.6.
(2) The probability that event F will occur is 0.4.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient
Here is my answer
Formula for event EUF i.e (either event E or event f or both occur) = E + F - (E&F)
In above, we are not provided with (E&F) therefore, answer is E i.e statement 1 and 2 are not sufficient.
