How do I find the probability of the event described. What is the probability of rolling a number less than or equal to 4?
Pr(less=4)=1-Pr(a 5 or 6)= 1-2/6=4/6
Thank you. I am not graping probability as well as I hoped.
To find the probability of rolling a number less than or equal to 4 on a fair, standard six-sided die, you need to determine the number of favorable outcomes and the total number of possible outcomes.
In this case, the favorable outcomes are the numbers 1, 2, 3, and 4, which means there are 4 favorable outcomes. The total number of possible outcomes is the number of faces on the die, which is 6.
To calculate the probability, divide the number of favorable outcomes (4) by the total number of possible outcomes (6):
Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes
= 4 / 6
= 2 / 3
≈ 0.6667 or 66.67%
Therefore, the probability of rolling a number less than or equal to 4 on a fair six-sided die is approximately 0.6667 or 66.67%.
