A mega-pack of markers contains red markers, black markers, and blue markers. There are 24 red markers in the pack. The probability of randomly choosing a red marker is 1 in 3. If the probability of randomly choosing a blue marker is 1 in 8, how many blue markers are in the pack? Will mark brainlist

Number of blue markers  = 9

Step-by-step explanation:

Given that there are 24 red markers.

Probability of randomly choosing a red marker is 1 in 3.

Probability of an event E is given as:

That means the ratio of red markers to total markers is 1:3.

Here number of favorable cases are 24 i.e. the number of red markers

and Total number of cases are equal to total number of markers.

Let T be the total number of markers.

As per definition of probability:

Also, given that the probability of choosing a blue marker is 1 in 8.

Let the number of blue markers be B.

As per definition of probability:

Hence, the answer is:

Number of blue markers  = 9

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
