A hat contains four balls. The balls are numbered 2, 4, 4, and 5. One ball is randomly selected and not replaced, and then a sec

The description that accurately explains how a fair decision can be made in this situation is : IF a ball with number 4 and 5 are picked you order the largest size, if a ball with number 4 and another with number 4 is picked you order the medium size, but if the balls picked are that of number 2 and 4, then you order a small size. The probability of each result occurring is a fair one.

<h3>Meaning of probability and full working</h3>

Probability is the degree of occurrence of an event. it can also be said to be the chance for an event to occur.

Probability helps us know the chance an event has to occur. The closer it gets to zero(0) the less chance it has to occur. The closer it gets to one(1) the more chance it has to occur.

(x%2)≠0 what does this mean - i dont understand the symbols

spin [16.1K]

% is used in a lot of programming languages as the modulo operator.

$a\%b=c\iff a\equiv c\mod b$

which is to say, the remainder upon dividing $a$ by $b$ is $c$ .

When you divide any integer by 2, you can get either a remainder of 0 or 1. So in your example, $x\%2\neq0$ refers to all numbers $x$ between 1 and 9 that are not perfectly divisible by 2. In other words, $x\%2\neq0$ refers to those $x$ that are odd. (This assumes $B$ is a subset of the integers.)
