Answer:
80%
Step-by-step explanation:
84/105=0.8
0.8=80%
The answer would be 25.65
Mean- 6.22
Median- 5
Mode- 11 (appears 2 times)
Range- 14
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%
B is 2 and C is 9. AB is 7, AC is 14 and AD is 21. The kine AD has been split into 3 equal sections which are 7 each
