Answer:
I thought it was 1/9
Step-by-step explanation:
favorable out comes are 4
and total out comes are 36
The probability that she rolls two numbers with a sum of 9 is 1/9 if the Elena rolls two cubes numbered 1 to 6.
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happeing of the event.
We have:
Elena rolls two cubes numbered 1 to 6.
The total outcome = 6×6
As there are two cubes with each cubes numbered 1 to 6
Total number of favourable outcomes = 4
Which are (3, 6), (4, 5), (5, 4), and (6, 3)
Now the probability P will be:
[tex]\rm P = \frac{4}{36}[/tex]
[tex]\rm P = \frac{1}{9}[/tex]
Thus, the probability that she rolls two numbers with a sum of 9 is 1/9 if the Elena rolls two cubes numbered 1 to 6.
