Mathematics
Two fair dice, each with at least $6$ faces, are rolled. On each face of each die is printed a distinct integer from $1$ to the number of faces on that die, inclusive. The probability of rolling a sum of $7$ is $\dfrac{3}{4}$ of the probability of rolling a sum of $10,$ and the probability of rolling a sum of $12$ is $\dfrac{1}{12}.$ What is the least possible number of faces on the two dice combined

simple random sampling
Step-by-step explanation:
A simple random sampling is a sampling technique in statistics in which a subset of the population (with population size N) is drawn by the researcher by selecting candidates for sample randomly such that the chances for each candidate to get selected remains equal asGiven : The names of 50 contestants are written on 50 cards.
here ,N= 50
So , the probability for each student to get selected =
.
The cards are placed in a bag, and three names are picked from the bag (which is a random action).
Hence, the sampling technique is used is "simple random sampling" .
