Generating random numbers

A game developer is working on a soccer video game.

This incomplete code segment is run when a player attempts a goal from outside the 6 yard box:

inGoal ← false
IF (<MISSING CONDITION>)
{
    inGoal ← true
    DISPLAY("Goal!")
}
ELSE 
{
    DISPLAY("Miss!")
}

At that distance, the code should give the player a 30% chance of making the goal.

Which of these can replace <MISSING CONDITION> so that the code works as intended?

🤔

This code is written in pseudocode. You can't actually run pseudocode, but we use it for planning programs and for thinking about code independently of specific programming language.

AP CSP exam questions use pseudocode, so it's helpful to become familiar with it.

Here is a reference for the pseudocode used here:

a ← expression

Evaluates expression and assigns the result to the variable a.

RANDOM(a, b)

Returns a random integer between a and b, including the possibility of both a and b.

IF (<condition>)
{
     <instructions 1>
} 
ELSE 
{
     <instructions 2>
}

If the <condition> is true, the first set of instructions is executed. Otherwise, the second set of instructions is executed. Each instructions block may contain additional nested IF/ELSE conditions.

**Relational operators**
Operator	Meaning
`a = b`	Equality
`a ≠ b`	Inequality
`a > b`	Greater than
`a < b`	Less than
`a ≥ b`	Greater than or equal
`a ≤ b`	Less than or equal
