Question

There are some pens of blue color in a bag. Reena takes one pen from the bag. The probability that the taken pen is of blue color is

Answer 1

Step-by-step explanation:

If 2 pens are drawn at random from the pack, NOT replaced and then another pen is drawn. We have to find the probability of drawing 2 blue pens and 1 black pen. We have a total of 4 + 2 + 3 = 9 pens out of which 4 are blue, 2 are red and 3 are black pens.

Answer 2

Answer:

Probability = 1 ( It will definitely happen)

Explanation :

Since there are only blue pen in the bag (According to your question), the probability of getting other colour pen is absolute zero. Thus we can get only blue colour pen therefore, the probability should be 1.

In other sense:

if E = getting blue pen,

P(E) = 1.
