|-11| + 52 = 50y - |-31| - 49y;

11 + 52 = y - 31;

63 = y - 31;

-y = -31 - 63;

-y = -94;

y = 94

11 + 52 = y - 31;

63 = y - 31;

-y = -31 - 63;

-y = -94;

y = 94

**User:** You have the numbers 1–24 written on slips of paper. If you choose one slip at random, what is the probability that you will not select a number which is divisible by 3 **Weegy:** 8 numbers in that sequence are divisible by 3, therefore 16 are not divisible by 3. The probability that you will NOT select a number divisible by 3 is 16/24, which can be reduced to 2/3 **User:** The probability of the complement of an event is ____ less than the probability of the event itself.

**User:** In a word game, you choose a tile from a bag, replace it, and then choose another. If there are 21 vowels and 15 consonants, what is the probability you will choose a consonant and then a vowel **Weegy:** The probability of a consonant is 15/(21+15), and the probability of a vowel is 21/(21+15). The probability of drawing them in sequence (with replacement) is
p(sequence) = (15/36)(21/36) = (5/12)(7/12)
p(sequence) = 35/144 **User:** Name the property the equation illustrates.
