Question 15 of 43
Andrews [41]

Answer:

Option A

Step-by-step explanation:

\frac{12}{25}  \times  \frac{11}{24}  \times  \frac{10}{23} \times  \frac{9}{22}

we start with 12 red marbles out of 25 marbles, that's the probability for the first.

in the second step we have one red marble less, wich also means one marble less overall

and so on

\frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22}

=  \frac{11880}{303600}

can be reduced by 1320 (step by step) to

\frac{9}{230}
