A biased dice was rolled and the scores recorded in the table below
dusya [7]

Given:

The table of score and frequency.

To find:

The probability that on the next roll the score will be 4.

Solution:

From the given table it is clear that the score 4 occurs 10 times.

Number of times the dice was rolled = 17 + 24 + 23 + 10 + 16 + 30

                                                             = 120

The probability that on the next roll the score will be 4 is

\text{Required probability}=\dfrac{\text{Number of times 4 occurs}}{\text{Number of times the dice was rolled}}

\text{Required probability}=\dfrac{10}{120}

\text{Required probability}=\dfrac{1}{12}

Therefore, the required probability is \dfrac{1}{12}.

How to write 8ft and 26in in standard notation
zmey [24]

The length in standard notation is 2.17 + 8 = 10.17 ft

<h3>How to write in standard notation? </h3>

A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules.

For example 9.5 billions years can be represented as follows;

9,500,000,000 years.

Therefore,  let's write 8 ft and 26 inches in standard form.

12 inches = 1 ft

26 inches = ?

cross multiply

length(ft) = 26 / 12

length(ft) = 2.16666666667

length(ft) = 2.17 ft

Therefore, the length in standard notation is 2.17 + 8 = 10.17 ft
