A bag contains 10 red marbles, 15 yellow marbles, 5 green marbles, and 20 blue marbles. Five marbles are drawn from the
bag.
What is the approximate probability that exactly two of the five are blue?

The approximate probability that exactly two of the five are blue is 0.3641

Step-by-step explanation:

Step 1

The total marble in the bag are

Step 2

When five marbles are drawn from the bag, we have to find the probability that exactly two of the five are blue.

=Probability that 2 blue marbles and 3 non blue marbles

Step 3

2 marbles should be drawn out of the 20 blue marbles and 3 non blue marbles out of 30 marbles

No of ways =

Total no of ways of drawing 5 marbles =

Probability=

Step 4

The approximate probability that exactly two of the five are blue is 0.3641

the solution is h=10 because you add 9 to each side of the equation.
