Answer 1

Solution :

1. The probability of an event that must occur is 1.

2.

True, Every probability is a number between 0 and 1 inclusive.

3.

Outcome

4.

probability that a family's first child will be born with Prader-Willi syndrome = 5/50000= 0.0001

5.

The probability of an event that cannot occur is 0.

6.

The sum of the probabilities of all possible outcomes of an experiment is 1.

7.

probability that event doesn't occur is =1-0.8= 0.2

8.

Any particular outcome or a group of outcomes is an sample space.

9.

The set of all possible simple events is the experiment.
