Question

A hat contains 10 pieces of paper numbered from - to 10. Find the probability

Answer 1

Using it's concept, it is found that the probabilities of each outcome are given by:

a) 0.01 = 1%.

b) 0.0111 = 1.11%.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Item a:

The number is replaced, hence for each trial there are 10 outcomes, and the probability of each is of 1/10, hence:

$p = \frac{1}{10} \times \frac{1}{10} = \frac{1}{100} = 0.01$

Item b:

Not replaced, hence for the second trial the probability is of 1/9, hence:

$p = \frac{1}{10} \times \frac{1}{9} = \frac{1}{9} = 0.0111$
