2. There are six ways we can have 7 and two ways, we can have 11 on two dice.
explanation:
When two dices are rolled, there are six possibilities of rolling a sum of 7.
357, 375, 537, 573, 735, 753. Therefore, '6' three-digit numbers can be formed.
hence the answer is 6 ways
5.
answer: four outcomes
solution:
When we spin the spinner there aqred four equally likely outcomes. When we roll the die, there are six different, equally likely outcomes. According to the Fundamental Counting Principle, if we spin the spinner and roll the die, the3 number of equally likely outcomes is 4 times 6 = 24.
