</span><span><u>Explanation</u> </span><span>The probability of an event is a chance of it happening. It is calculated as; Probability =(fouvarable outcome)/(total outcome) Since we are finding the probability of no girl will be chosen, it is like finding the probability of choosing 3 boys. The probability of choosing the first boy =4/12 The probability of choosing the second boy =3/11 The probability of choosing the third boy =2/10 The probability of choosing the 3 boys will be, =4/12×3/11×2/10 =24/1320 =1/55 </span></span>
Explanation: If you add 3X + 5X you get 8X since you can’t add them with the whole numbers without a variable. After that you add 4 + -6 (4 - 6) either that or its 8X + 10
