If you roll a 6-sided die 90 times, what is the best prediction possible for the number of times you will roll an odd number?

half of the faces are odd

so, 45

15

To find the best prediction for the number of times you will roll an odd number when rolling a 6-sided die 90 times, we can use probability.

The die has 6 possible outcomes: 1, 2, 3, 4, 5, and 6. Out of these, 3 are odd numbers: 1, 3, and 5.

Since each roll is independent, the probability of rolling an odd number on any given roll is 3/6, which simplifies to 1/2.

To predict the number of times you will roll an odd number, multiply the probability of rolling an odd number on each roll (1/2) by the total number of rolls (90):

Prediction = Probability of rolling an odd number on each roll * Total number of rolls
= (1/2) * 90
= 45

Therefore, the best prediction possible for the number of times you will roll an odd number is 45 times.

To find the best prediction for the number of times you will roll an odd number, we need to consider that each roll of the dice is an independent event with a 1/2 chance of rolling an odd number and a 1/2 chance of rolling an even number.

Since you are rolling a 6-sided die, there are 3 odd numbers (1, 3, and 5) and 3 even numbers (2, 4, and 6) on the die.

To calculate the best prediction, you can multiply the probability of rolling an odd number (1/2) by the number of rolls (90). This gives us:

Best prediction = (probability of rolling an odd number) * (number of rolls)
= (1/2) * 90
= 45

Therefore, the best prediction for the number of times you will roll an odd number when rolling a 6-sided die 90 times is 45.
