Question

These marbles are placed in a bag and two

of them are randomly drawn.
What is the probability of drawing two
yellow marbles if the first one is placed back
in the bag before the second draw?
Give your answer as a ratio, reduced to
simplest terms.
?
Hint: Multiply the probability of the 1st Event by the
probability of the 2nd Event to get your answer

Answer 1

There are 10 marbles, 2 are yellow

The probability would be 2:10 but in simplest form 1:5

The probability of picking both the same = 1:5 x 1:5 = 1:25
