Detailed explanation-1: -To find out how many times a cube will land a number less than 3 out of 450 times, we need to find the expected value. Hence, the best prediction for the number of times a cube will land on a number less than 3 is 150.
Detailed explanation-2: -The answer is 5:6. The theoretical probability of rolling a number less than 6 on a number cube is 5:6.
Detailed explanation-3: -A number cube is rolled three times. An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on the second roll, and an even number on the third roll). The 8 outcomes are listed in the table below. Note that each outcome has the same probability.
Detailed explanation-4: -Explanation: For each number, there is a 16 probability of rolling it (so 16 for the 1 and also 16 for the 4).
