Given:
A regular die
Required
The probability of obtaining a 2 digit in 1 roll
First, the possible outcomes has to be listed; This is referred to as Sample Space (S);
The Sample Space is as follows
Let T represent the outcomes showing two digit such that n(T) represent the number of outcomes showing two digit
Since there's no two digit in the sample space;
T = {}
The probability is then calculated as follows;
Answer:
Michelle is 14 years old.
Step-by-step explanation:
The only logical explanation for the two being two years apart in age and Michelle being twice as old ten years ago is if Michelle was 4 years old and Nicole was 2 years old ten years ago. To verify this, we can use a System of equations.
Let:
N = Nicole's Age
M = Michelle's Age
N + 2 = M
2n-10 = M
Since both equal Michelle's age, we can make a two step equation out of it.
N + 2 = 2n - 10
2 = N - 10
12 = N
We've found Nicole's age, allowing us to plug the answer back into the variable to get Michelle's.
<u>N + 2 = M</u>
12 + 2 = 14
