probability of an event is given by the formula
p=x/s, where x is the set of all the values, which result in a success and s is the set of all possible values, called the sample set
now here, a die has numbers from 1 to 6. so, the sample space is 6.
the number should be greater than 3 and even. first of all, the numbers greater than 3 on a die are 4,5 and 6. but the even numbers among these are only 4 and 6. so, x is 2
now probability is x/s=2/6 or when simplified, it is 1/3.

2 in 6 which= 1 in 3

The number rolled is greater than 3 and even.
The possibilities are 4 and 6.
There are a total of 2 possibilities.
There are totally 6 numbers on a die.
The probability = (No. of possibilities)/(Total number)
= 2/6
= 1/3 (simplified)
You can probably roll a number greater than 3 and even once every 3 tries. The true success rate depends on practice. According to theory, The probability of success is once every 3 tries. But if you try it in actual life, you might roll such a number all 3 times, twice in 3 tries, once or not even once in 3 tries.

There are 6 numbers on a die. There are only even 2 numbers greater than 3 (4 and 6). Th probability is therefore 2/6, or when simplified 1/3.

Since there are 6 sides on a single die, and you are rolling it once, there are six total possible outcomes. There is only one digit greater than 5 (6), and 2 less than 3 (1 and 2). This adds up to 3 of the possible 6 outcomes. Therefore, you take 3 and divide it by six. Te final answer is 1/2 or 50%. Hope this helps!

the probability of getting a number greater than 3 and even is 1/3

I did it slightly differently, but the answer is the same.
To roll a number higher than three, the odds are 3/6
The odds that this number will be even are 2/3
Multiplying2/3*3/6, you have 6/18 chances of meeting both conditions,
which is still 1/3.

the probability of number rolled in the dice is 1by6,since a die has 6 faces.
as 4 and 6 are evn and greater than 3,the probability of rolling 4 and 6 is 1by6 multipliedby 2,then we get 1by3.
hence the answer is 1by3

the number rolled must be 4 or 6
probability=2/6=>1/3

the numbers that are greater than three and even are 4 and 6, so there is a 2 in 6 chance.
