An experiment consists of tossing 4 unbiased coins simultaneously. What is the number of simple events in this experiment?
kupik [55]

The number of simple events in this experiment according to the probability is 16.

According to the statement

we have to find that the number of simple events in this experiment.

So, For this purpose, we know that the

Simple events are the events where one experiment happens at a time and it will be having a single outcome. The probability of simple events is denoted by P(E) where E is the event.

And according to the given information is:

Total number of coins tossed is 4.

then

the simple events become

Simple events = no. of coins * total coins tossed

Simple events = 4*4

Now solve it then

Simple events = 16.

So, The number of simple events in this experiment according to the probability is 16.
