Answer:
112 candles
Step-by-step explanation:
We can simply add up the 5 numbers of candles, or we can take advantage of the invention of multiplication to replace repeated addition. The number of candles altogether is the sum of the numbers of candles in each of the 5 boxes.
16 + 4×24 = 16 +96 = 112
The total number of candles is 112.
Answer:
480 ways
240 ways
Probability = 1/7
Step-by-step explanation:
Given:
Number of student = 5
Number of teacher = 2
Computation:
1. Number of ways can they line up, side by side, for a picture.
5! × 2! × 2
480 ways
2. Number of ways can they line up if they must have the teachers on both sides of the picture.
5! × 2!
240 ways
3. Probability that the two teachers occupy two of the three middle slots.
³C₂ × 5! × 2!
720 ways
Total number = 7! = 5,040 ways
Probability = 720 / 5,040
Probability = 1/7
