Math Problem Statement

Two dice are thrown and the product of the two numbers shown is calculated. Find the probability that the product is 6.

Solution

To solve this problem, we need to calculate the probability that the product of the numbers shown on two thrown dice equals 6.

Step 1: Total Possible Outcomes

When two dice are thrown, each die has 6 faces, so the total number of possible outcomes is: 6×6=366 \times 6 = 36 These are all the possible combinations of numbers that can appear on the two dice.

Step 2: Identifying the Pairs That Result in a Product of 6

We now identify all possible pairs (x,y)(x, y), where xx is the number on the first die and yy is the number on the second die, such that the product x×y=6x \times y = 6.

The pairs are:

  • (1,6)(1, 6): 1×6=61 \times 6 = 6
  • (2,3)(2, 3): 2×3=62 \times 3 = 6
  • (3,2)(3, 2): 3×2=63 \times 2 = 6
  • (6,1)(6, 1): 6×1=66 \times 1 = 6

Thus, there are 4 favorable outcomes.

Step 3: Calculating the Probability

The probability is given by the ratio of favorable outcomes to total outcomes: P(product is 6)=Number of favorable outcomesTotal number of outcomes=436=19P(\text{product is 6}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{4}{36} = \frac{1}{9}

Final Answer:

The probability that the product is 6 is 19\frac{1}{9}.
