5p - 3q = -39
- (-2p - 3q = 3)
==> 7p = -42 ==> p = -6
==> p = -6
-2(-6) - 3q = 3 ==> 12 - 3q = 3
==>p = -6
-3q = 3 - 12 ==> -3q = -9
==> p = -6
q = 3
Answer: p = 0.56
Step-by-step explanation: from the question, probability she passed the first course = 0.7
Probability she passed the second course = 0.8
Probability she passes both courses means probability she passes the first course "and" probability she passes the second course.
Probability she pass both courses = 0.7 * 0.8 = 0.56
Note that "and" in probability means multiplication.
