Question

Crosby has a collection of marbles of different sizes and colors. Red Green Big 9 8 Small 11 16 What is the probability that a randomly selected marble is big and red? Simplify any fractions

Answer 1

We will have that the probability is the following:

*First: We determine that the total of possibilities is:

$9+8+11+16=44$

*Second: Since we can see that from all those only 9 are big and red, then the probability of getting at random a big red marble is:

$p=\frac{9}{44}$
