a) What is the probability of rolling an even number?
b) What is the probability of rolling an odd number?
c) What is the probability of rolling a number that is greater than 3?
d) What is the probability of that you do NOT roll a four?
e) What is the likelihood of rolling a number less than 4?.
f) What are the chances of rolling a prime number?
Answer for sheet # 243
a) Since there are 3 even numbers on the sides of a cube (2,4 and 6),
the number of desirable outcomes is 3.
There are 6 possible outcomes (1,2,3,4,5 and 6).
Probability of getting an even number is 3/6 = 1/2
b) Three odd numbers; 1, 3, and 5
Probability of getting an odd number is = 3/6 = 1/2
c) There are three number greater than 3; 4, 5, and 6
Probability of getting a number greater than 3 is 3/6 = 1/2
d) There is only one side with number '4".
Probability of getting 4 is = 1/6
e) Three numbers are less than 4; 1, 2, and 3
Probability of getting a number less than 4 = 3/6 = 1/2
f) There are three prime numbers; 2, 3, and 5.
Probability of getting a prime number is = 3/6 = 1/2
