FAQs (Frequently Asked Questions)

1. If P(E) = 0.01, what is the probability of ‘not E’?

As we know 

P(E)+P(not E) = 1

It is given that, P(E) = 0.01

So, P(not E) = 1-P(E)

That is, P(not E) = 1-0.0

∴ P(not E) = 0.99

2. A box contains 5 red marbles, 8 white marbles, and 4 green marbles. One marble is removed from the box at random. What is the probability that the marble removed will be red?

The Total no. of balls = 5+8+4 = 17

P(E) = (Number of favorable outcomes/ Total number of outcomes)

So, Total number of red balls = 5

P (red ball) = 5/17 = 0.29

Thus, the probability of obtaining a red ball is 0.29.

It is said that the probability of an event to take place will range between 0 and 1, that is the probability will be between greater than or equals to 0 and less than or equals to 1. It shows that it is not Mathematically possible to have probability values less than 0 or more than 1.
