Question

If the die is rolled 100 times and the number of times 6 appeared was noted.The probability of 6 is 2/5 then how many times 6 occur.

Answer 1

AnswEr :-

Total number of trials = 100

Let x be the number of times occurring 6.

$\sf {Probability\ of\ an\ event = \frac{Frequency\ of\ the\ event\ occurring}{Total\ number\ of\ trials}}$

$\sf {\frac{x}{100}=\frac{2}{5} }\\\\\sf {x = \frac{100\times 2}{5} }\\\\\sf {x = \frac{200}{5} }\\\\\sf {x = 40}$

Answer 2

Answer:

$\bf \: Question \:$

If the die is rolled 100 times and the number of times 6 appeared was noted.The probability of 6 is 2/5 then how many times 6 occur.

GIVEN:-

$\bf \: total \: number \: of \: trials = \red{ 100}$

$\bf \: Let \: x \: be \: the \: number \: of \: times \: occuring \: \red{6. }$

$\bf \: Find \: it$

$\bf \: how \: many \: times \: 6 \: occur.$

We know,

$\sf {Probability\ of\ an\ event = \red {\frac{Frequency\ of\ the\ event\ occurring}{Total\ number\ of\ trials}}}.$

$\begin{lgathered}\sf {\frac{x}{100}=\frac{2}{5} }\\\\\sf {5x = 200}\\\\\sf {x = \frac{200}{5} }\\\\\sf {x = \green{ 40}}\end{lgathered} </p><p>.$
