(1/2) 50 POINTS QUESTION!!!!!

1. Not a prime number
2. a number greater than 6
3. not a multiple of 4
4. a prime number between 2 and 6
(SPAM OR FALSE ANSWERS WILL BE REPORTED!!)
Answers
Answer:
(1) 1/2, (2) 0, (3) 1/2, (4) 1/2
Step-by-step explanation:
To find he probability you firstly have to consider the number of outcomes possible.. like in the first question
1. Not a prime number: There are three prime numbers found on a dice which are 2 , 3 and 5. Meaning that the numbers on the dice we are looking for are 1 , 4 and 6. so we make a fraction using the number of possible outcomes over the total number of numbers on the dice which is 6 , our answer will be 3/6 which is then simplified as 1/2.
2. a number greater than 6; Well, we all know that numbers on a dice do not exceed 6 right? So there are 0 possible outcomes of it being greater than 0 ... our fraction will then be 0/6 which can be simplified as just 0.
3. not a multiple of 4; the numbers from 1-6 that can enter 4 without a remender are 1 , 2 and 4 itself so, there are 3 possible numbers out of 6.making our equation 3/6 or just 1/2.
4. a prime number between 2 and 6: for this one, the only prime numbers between 2 and 6 are 2 ,3 and 6. so we have another 3/6 which leads to 1/2.
