If a single die is tossed once, find the probability that you roll 6 or 5 or 1.
is it 1/6 ?
or 1/2 ?
3 chances out of 6
What do you think?
1/2
half
Right! 1/2
To find the probability of rolling a 6 or 5 or 1 on a single die, you need to determine the number of favorable outcomes (rolling a 6, 5, or 1) and the total number of possible outcomes (numbers 1 to 6 on the die).
In this case, the favorable outcomes are rolling a 6, 5, or 1, and there are three of them. The total outcomes are numbers 1 to 6 on the die, so there are six of them.
Therefore, the probability of rolling a 6 or 5 or 1 on a single die toss is given by the formula:
Probability = Favorable Outcomes / Total Outcomes
In this case, the probability is:
Probability = 3 / 6
Simplifying, we get:
Probability = 1 / 2
So, the correct answer is 1/2.
