Random answer Android studio Kotlin

I'm a beginner and I wanted to make a code that will print "yes" or "no" on random when the button is clicked. (Using kotlin) here's my code package com.example.calculator

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*
import android.view.View

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        fun buttonPressed(view: View){
            val randomword = Random. ("yes" or "no")
            textView.text = randomword
        }
    }
}
