Probability -an Experimental Approach

In a biased coin probabilities are equal.

What is biased die?

What is the difference between biased and unbiased coin?

What is biased in probability?

Find the favourable outcome of getting a number greater than $6$ when a die is rolled.

What is the difference between sample space and an event?

A dice is thrown $67$ times and the number $5$ appeared on the dice $23$ times. Now, in a random throw of a dice, what is the probability of getting a number $5$.

Write the sample space in tossing two coins simultaneously.

Find the number of favourable outcomes of getting a sum $5$ when two dice are thrown.

You buy a lottery ticket and win the jackpot.

$\mathrm{P}\left(\mathrm{E}\right)+\mathrm{P}(\mathrm{not} \mathrm{E})=$ _____.

Eleven bags of wheat flour, each marked $5 \mathrm{kg}$, actually contained the following weights of flour (in $\mathrm{kg}$).

$4.97, 5.05, 5.08, 5.03, 5.00, 5.06, 5.08, 4.98, 5.04, 5.07, 5.00$

Find the probability(in fraction) that any of these bags chosen at random contains more than $5 \mathrm{kg}$ of flour.

Given below is the frequency distribution table regarding the concentration of sulphur dioxide in the air in parts per million of a certain city for $30$ days.

Find the probability(in the lowest form of fraction) of the concentration of sulphur dioxide in the interval $0.12-0.16$ on any of these days.

$1500$ families with $2$ children were selected randomly and the following data were recorded.

If a family is chosen at random, compute the probability(up to four decimal places) that it has no girl.

On one page of a telephonic directory, there were $200$ telephone numbers. The frequency distribution of their unit place (for example, in the number $25828573$, the unit place digit is $3$) is given below.

Without looking at the page, the pencil is placed on one of these numbers, i.e., the number is chosen at random. What is the probability that the digit in its unit place is $5$?

In a cricket match, a batsman hits boundary in $20\%$ of the balls he played. Find the probability that he did not hit a boundary.

The probability that a non-leap year has $53$ Sundays is $\frac{m}{n}$. Then find the value of $n+m$

Product of the numerator and denominator of probability of choosing a vowel randomly from the word 'EXAMINATION' is

Find the sum of numerator and denominator of the probability of choosing a day from a week.

If an odd number is randomly selected from first $30$ natural numbers then find the numerator of required probability obtained.
