Final answer:
The probability of Jill passing both her statistics course and her history course is determined using joint probability. Joint probability is the probability of two or more events happening together.
Step-by-step explanation:
The probability of Jill passing both her statistics course and her history course is determined by using joint probability. Joint probability is the probability of two or more events happening together. In this case, the joint probability is the probability of passing both courses.
To find the joint probability, you multiply the individual probabilities of passing each course. Let's say the probability of passing the statistics course is 0.8 and the probability of passing the history course is 0.7. The joint probability would be 0.8 * 0.7 = 0.56.
