True: A face of a polyhedron is simply a flat boundary that helps forms the 3D solid.
Answer:
Explanation:
The theoretical probability, P (A), of an event, A, is:
- P(A) = number of outcomes of event A / total number of possible outcomes
For 10 cranberry and 15 strawberry juices, the number of outcomes for two strawberry juices are:
- Combination of 15 strawberry juices chosen in two:

The total number of possible outcomes is:
- Combination of 25 juices chosen in two:

Thus, the probability of randomly picking two strawberry juices is:
- P (two strawberry juices) = 105/300 = 7/20
Note that you can obtain it as the product of the probabilities that the first juice is a strawberry juice and the second juice is also strawberry juice:

To do this, multiply 3/4 by 1/2 and you end up with 3/8 lb. or 0.375 lb.
