When a subtraction problem is performed, the answer is the difference between the two numbers being subtracted.
Subtraction is the mathematical operation of finding the result when one quantity is taken away from another.
For example, if you have the subtraction problem 7 - 3, the answer would be 4, as you are subtracting 3 from 7, resulting in a difference of 4.
Similarly, in the subtraction problem 15 - 8, the answer would be 7, as you are subtracting 8 from 15, resulting in a difference of 7.
In general, when performing a subtraction problem, you are finding the numerical difference between two values.

Answer:
2 successes = 80/243
0 successes = 32/243
at least 3 successes = 51/243
Step-by-step explanation:
Lets suppose we had the following sequence of 5 throws:-
2 or 3, 2 or 3 , then NOT 2 or 3 on last 3 throws
Probability of this is
1/3 * 1/3 * 2/3 * 2/3 * 2/3 = 8/243
There are (5*4) / 2 = 10 ways of having this result ( that is the number of combinations of 2 from 5 = 5C2 ).
So Prob(2 successes) = (8/243) * 10 = 80/243
Prob ( No successes) = (2/3)^5 = 32/243
Probability of 3 successes = 1/3 * 1/3 * 1/3 * 2/3 * 2/3 * 5C3
4/243 * 10 = 40 / 243
Probability of 4 successes = (1/3)^4 * 2/3 * 5C4
= 10/243
Probability of 5 success = (1/3)^5 = 1 / 243
Prob(at least 3 successes) = 51/243

Probability of 4 successes = (1/3)^4 * 2/3 * 5C4
= 10/243
Probability of 5 success = (1/3)^5 = 1 / 243
Prob(at least 3 successes) = 51/243
