Answer:
do you have a picture of the Graph?????
So,
Since you can only take two one-credit courses every six months, you can earn 2 credits every six months, and 4 credits in one year. Multiplying that by 3, you get 12 credits in 3 years.
It will take 3 years to get the degree.
Since the sum of the probabilities of all possible outcomes must be 100%, we can deduce the following:
- Cooking in under 20 minutes: 10%
- Cooking between 20 and 30 minutes: 85%
- Cooking in more than 30 minutes: 5%
In fact, the probabilities of cooking in less than 20 or more than 30 sum up to 15%, which means that the remaining outcome (i.e. cooking time between 20 and 30) must complete this probability to 15, and in fact 15+85=100.
That being said, all three answers are simply a combination of these three scenarios: let C be the cooking time, for aesthetic reasons:
