A compound event, in probability theory is an event which is made up of two (or more) simpler events. Thus, tossing two coins in a compound event made up of tossing one coin and tossing another coin. Getting soaked in rain consists of the simple events that it rains (where you are) and you are outdoors without an umbrella (at that time).

Since each event is independent, the probability remains at 0.5.

Probability

Yes, it can.

The probability of an event is the number of favourable outcomes divided by the total number of possible outcomes. What is the total number of possible outcomes of tossing a number cube? 6 How many outcomes are favourable to the event of getting a five? 1 So the prob is 1/6 or 0.16667

If the probability of an event is p, then the complementary probability is 1-p.

A coin flip

The probability is 0. Consider the event of tossing a coin . The possible events are occurrence of head and tail. they are mutually exclusive events. Hence the probability of getting both the head and tail in a single trial is 0.

No, it is not.

A certainty.

First event is to roll a 3 or 6 on a die, which gives you a probability of 2 out of 6. Second event is tossing a heads on a coin, so a probability of 1 out of 2. Since both chances are not related, you can multiply both chances: 2/6 times 1/2 = 1/6 = 0,166666...

Probability (P) of the Event (E).To obtain the probability, use the formula P(E) =No. of trials when event occuredTotal No. of trialsWhere 'trial' refers to doing something to observe the outcome e.g. tossing a coin.Outcome may refer to (in that case) getting Head or Tail.
