Answer:
The correct answer is 125 times.
Step-by-step explanation:
Let's recall the formula of the probability:
Probability = Number of favorable outcomes/Total number of possible outcomes, therefore:
Probability of rolling a number cube and landing on an odd number = 3/6 = 1/2 because 1, 3 and 5 are the odd numbers out of 6 in a number cube.
It means that if we roll the cube, we have 50% of probability of landing on an odd number, in consequence:
If we roll the number cube 250 times, the number of times it will land an odd number is:
250 * 50% = 250 * 0.5 = 125
The correct answer is 125 times.
