Question

Express the probability that a die will land on a number less than 5 as a fraction

Answer 1

ANSWER

$P(E)=\frac {2} {3}$


EXPLANATION


When a die is tossed, the possible outcomes are

S={1,2,3,4,5,6}.


$n(S)=6$




The event of getting a number less than 5 is

E={1,2,3,4}

$n(E) = 4$

$P(E)=\frac{n(E)} {n(S)}$


$P(E)=\frac {4} {6}$


$P(E)=\frac {2} {3}$

Answer 2

Answer:

P( less than 5) = 2/3

Step-by-step explanation:

The die can land on 1,2,3,4,5,6

There are 4 choices that are less than 5.  {1,2,3,4}

P( less than 5) = number of choices less than 5/ total choices

                        = 4/6

We can simplify by dividing the top and bottom by 2

P( less than 5) = 2/3
