Five students, adriana, ben, chandra, diana, and ernesto, would each like one of the four spots at the regional science fair. their names are placed in a hat, and four names are chosen at random to decide who attends the fair. what is the theoretical probability that chandra will be chosen as one of the science fair participants?

25%
60%
75%
80%

The theoretical  probability that among randomly  selected 4 names from a hat with 5 names will be Chandra's name can be calculated using formula:

1. The number of all possible outcomes. You can choose 4 names from 5 in

2. The number of all favorable outcomes. Only one of these 5 possible selections will not contain Chandra's name, then the number of all favorable outcomes is 4.

3.  Thus, the theoretical probability is

correct choice is D
