Question

You rolled a number cube 50 times. Your results are shown in the table below.

What is the experimental probability of rolling a 3?


Number Frequency

1 4

2 9

3 6

4 12

5 9

6 10



Hope this isn't to confusing :(
(4,9,6,12,9,10 are under Frequency)

Answer 1

Answer:

hi mate

ur answer is 3/25

hope it helps...

Answer 2

$A \: number \:cube \: rolled \: 50 \:times$

$\underline { \blue { Results \: table : }}$

$\begin {tabular} {|c|c|c|c|c|c|c|} </p><p>\cline {1-7} Number&1&2&3&4&5&6 \\</p><p>\cline {1-7} Frequency &4&9&6&12&9&10\\</p><p>\cline {1-7} </p><p>\end {tabular}$

$\pink { Number \:of \: total \: possible \: outcomes }\\= 50$

$\orange { Number \:of \: favourable \: outcomes } \\= frequency \:of \: number \: 3 \\= 6$

$\red{ Probability \:of \: rolling \:number \:3} \\= \frac{ Number \:of \: favourable \: outcomes }{Number \:of \: total \: possible \: outcomes} \\= \frac{6}{50} \\= \frac{3}{25}$

Therefore.,

$\red{ Probability \:of \: rolling \:number \:3}\\\green {= \frac{3}{25}}$
