Questions & Step-by-Step Solutions
Two dice are thrown simultaneously. What is the probability that the sum of the numbers on the dice is 7?
Step 1: Understand that we are throwing two dice, and each die has 6 faces numbered from 1 to 6.
Step 2: Calculate the total number of possible outcomes when throwing two dice. Since each die has 6 faces, the total outcomes are 6 (from the first die) multiplied by 6 (from the second die), which equals 36.
Step 3: Identify the specific outcomes where the sum of the numbers on the two dice equals 7. These outcomes are: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1).
Step 4: Count the number of outcomes that give a sum of 7. There are 6 outcomes that result in a sum of 7.
Step 5: Calculate the probability of getting a sum of 7 by dividing the number of favorable outcomes (6) by the total number of outcomes (36). This gives us 6/36.
Step 6: Simplify the fraction 6/36 to get the final probability, which is 1/6.
