Answer:
Therefore,
Probability for getting a number less than 4 is
Step-by-step explanation:
Given:
Let the Experiment be of rolling a 6 sided,
Let the sample space of the above experiment be S,
S = { 1, 2, 3, 4, 5, 6 }
n(S) = 6
Let A be the event of getting a number less than 4,
A = { 1 , 2, 3, }
n(A) = 3
Then the probability for getting a number less than 4 is given by.
Substituting the values we get
Therefore,
Probability for getting a number less than 4 is
Answer:
76 comic books
Step-by-step explanation:
First we must structure a formula in order to solve for the number of comic books that Michelle initially had. The formula for this problem would be:
x · \frac{1}{2}x + 18 = 56
In order to solve for x, the initial number of comic books Michelle had, you would need to subtract 18 from 56. You would then have 38. So:
x · \frac{1}{2}x = 38
Next, you'd need to get rid of the \frac{1}{2}. In order to do that, you would divide \frac{1}{2} by 38. Now, we should be left with:
x · x = 76
Now, we don't really need both x's. We can already conclude that x is equal to 76, since the following is true:
76 comic books - \frac{1}{2} (76) sold + 18 bought = 56 comic books left.
Therefore, your answer is 76 comic books.
