Think of 5 situations with equally likely events and find the sample space

If A and B are mutually exclusive events and S is the sample space such that P(A)=(1)/(3) P(B) and S=AuuB , then P(A)= .............

Give examples of 5 experiments that have equally likely outcomes and five more examples that do not have equally likely outcomes

An experiment consists of tossing a coin and then throwing it second time if a head occurs on the first toss, then a die is rolled once. Find the sample space.

Can you think of a situation where we deliberately want to make a species extinct? How would you justify it?

The probability of happening of an event A is 0.5 and that of B is 0.3. If A and B are mutually exclusive events, then find the probability that neither A nor B happen.

A coin is tossed. If it shows tail, we draw a ball from a box contains of 2 red and 3 black balls. If it shows heads, we throw a die. Find the sample space of this experiment.
