Question

bag contains eight red marbles and
seven blue marbles. You randomly pick a
marble and then pick a second marble
without returning the marbles to the bag.
The first marble is red and the second
marble is blue.

Answer 1

The probability of getting first marble is red and the second

marble is blue is 4/15.

What is probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes.

Given that:

Number of red marbles= 8

Number of blue marbles= 7

Total Number of marbles= 8+7 = 15 marbles.

P(red Marble) =$\frac{8}{15}$

No replacement, now the total marbles = 14

P( blue marbles) = 7/14

Now, P( first marble is red and the second marble is blue.)

= 8/15*7/14

= 4/15

Hence, the probability of getting first marble is red and the second

marble is blue is 4/15.
