First one b ≤ 9 good luck
To solve this problem, let us recall that the formula for
probability is:
Probability = total number of successful events / total
events
Where in this case, an event is considered to be successful
if the sum is 3 on the pair of six sided dice.
First, let us calculate for the total number of events. There
are 6 numbers per dice, therefore the total number of combinations is:
total events = 6 * 6 = 36
Next, we calculate for the total number of combinations
that result in a sum of 3. We can identify that there are only two cases that
result in sum of 3. That is:
1st case: first dice rolls 1, second dice
rolls 2
2nd case: first dice rolls 2, second dice
rolls 1
Hence, total number of successful events = 2. Therefore the
probability is:
Probability = 2 / 36 = 1 / 18 = 0.0556 = 5.56%
Answer: The Numbers are 15 and 39
Step-by-step explanation: 2(15) + 9 = 39
The number of small chocolate-bars sold is 272.
<h3>What is a ratio? </h3>
Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is another value. The sign used to represent ratios is :.
<h3>What is the number of small chocolate bars sold?</h3>
The number of packs small chocolate bars sold = (ratio of he number of small chocolate bars sold / sum of ratios) x number of chocolate bars sold
(5/7) x 95 = 67.8 = 68
The number of small chocolate bars sold = 68 x 4 = 272
