Question

In 100 throws a dice ,4 is obtained 36 times .in a random throw ,what is the probability of getting a 4

Answer 1

Given

In 100 throws 4 is obtained 36 times

It means 46 chance are remaining

there are 6 faces in a dice

TO FIND

probability of getting 4

SOLN

the chance of getting 4 will be as equal to the probability of getting other numbers

In 64 remaing chance getting other no will be 64 devided by 6 ( because there are 6 faces of a cube)

Answer 2

Given.

In 100 throws of a die, a 4 is obtained 36 times.

To find,

In a random throw, the probability of getting a 4.

Solution,

Probability of getting a 4 = Number of times 4 is obtained/Total number of times the die is thrown.

∴ Probability of getting a 4 = 36/100

                                             ⇒ 9/25           (∵ On dividing by 4)

∴ The probability of getting a 4 is 9/25
