<p>Carol has 5 scarves and 5 sweaters , and each scarf matches a different sweater . If she chooses one of those scarves and one of those sweaters at random , what is the probability that they will not match?
I have a problem with this question, so please help me. </p>
<p>I am not good at all at the explaining anything but i will give it a try. :D</p>
<p>First of all, you should know all the combinations.5 sweater times 5 scarves gives us 25 combination.After that you should know the combination the WILL MATCH.They are 5,so 25-5= 20 that doesn’t match.Lastly, you should put it like this 20/25 or 4/5.</p>
<p>meumeu,
Actually you could break down the problem even simpler.
If you start by picking 1 scarf, what is the probability of picking a matching sweater. 5 sweaters to pick from and only 1 matches. 1/5 match or 20%. 4/5 don’t match or 80%.</p>
