Probability problems

Notice that the probability of drawing an E is 3 10 3 10 and the probability of drawing an S is 2 10 2 10; adding those together, we get 3 10 + 2 10 = 5 10 3 10 + 2 10 = 5 10. Look at the numerators in the fractions involved in the sum: the 3 represents the number of E tiles and the 2 is the number of S tiles.

In other words, in order to get a new value of seed, multiply the old value by 7621, add 1, and, finally, take the result modulo 9999. Now, assume, as in the example above, we need a random selection from the triple 1, 2, 3. That is, we seek a random integer n satisfying 1 ≤ n ≤ 3. The formula is. n = [3 × seed /9999] + 1.Number activities for kids include creating a scale, discovering probability, and creating a secret code. Learn more about number activities for kids.
