Question

The probability of getting an even number when a fair dice is rolled

once is................​

Answer 1

Answer:

On a 6 sided dice there are 3 possible even number...” 3/6 and 50/100 are both the same fraction, 1/2! So the probability of rolling an even number on both of those dice is the same! The number of sides would not change the answer.

Answer 2

Answer:

The sample space has 6 possible outcomes-  

S={1,2,3,4,5,6}.

Let all outcomes are equally likely(fair dice).

Hence Probability of any one outcome occurring= 1/6.

The event that we get that an even number on tossing the die can occur in 3 possible ways.  

Let E denote this event.

E={2,4,6}

Now P(E)= 3×
