Answer:
It is not
Step-by-step explanation:
Because "Kira" lol is doing something like saying 1-3 = 2 which it doesn't you have to regroup in this case and you can't do what she did, though what she did with her whole numbers is correct
I hope this helps!
The two rolls of the number cube are independent events because
the result of 1 roll does not affect the result of the other roll.
To find the probability of two independent events, we first find
the probability of each event, then we multiply the probabilities.
We can find the probability of an event using the following ratio:
number of favorable outcomes/total number of outcomes
Since there is only one way to roll a 3 and there are six
possible outcomes, 1, 2, 3, 4, 5, and 6, the probability of rolling a 3 is 1/6.
Since there is also only one way to roll a 2 and there are
six possible outcomes, the probability of rolling a 2 would be 1/6.
Now we multiply the probabilities.
1/6 x 1/6 is 1/36.
So the probability of rolling a 3 and a 2 is 1/36.
T = # of text messages
$91.50 = 0.45t + $50
Subtract 50 from both sides
$41.50 = 0.45t
divide by 0.45
