To determine

To calculate the probability

Answer to Problem 11PG

  $P(4)=0.2$

Explanation of Solution

Given information:

Outcome	Frequency
1	4
2	6
3	5
4	3
5	7

Formula used:

  $P(a)=\frac{NumberOfFavorableOutcomes}{TotalOutcomes}$

Calculation:

Total number of items,

  $4+6+5+3+7$

On solving,

  $15$

Frequency of 4,

3

On solving,

  $15$

Substituting the values,

  $P(4)=\frac{3}{15}$

On solving,

  $P(4)=0.2$
