Question

A jar contains 10 marbles marked with the numbers 1 though 10 you pick a marble at random what is the probability of not picking the marble marked with the number 6 enter your answer as a simplified fraction

Answer 1

Answer:

The probability of marble getting marked as 6 is 0.9

Step-by-step explanation:

Total number of marbles = 10

The probability is the ratio of the number of elements in the event to the number of elements in the sample space.

Here the number of elements in the sample space = 10

The probability of getting a marble marked as 6 is

$P(E)=\frac{1}{10}$

The probability of not getting the marble marked as 6 is

$P((E')=1 - P(E)\\P(E') = 1- 0.6= 0.4$

$P(E') = \frac{9}{10}$
