Question

a die is thrown once . what is the probability of getting a number which is divisible by 3​

Answer 1

Answer:

There are six sides on a dice with numbers ranging from 1 to 6 (every digit once). Nos divisible by 3 are 3 and 6

Probability is the (no of desired events) / (Total number of events)

Since in this case the desired events are two (3 and 6) the probability is 2/6 i.e 1/3

Answer 2

Given :

• A die is thrown.

To Find :

• Probability of getting a number which is divisible by 3.

Solution :

$\longmapsto\tt{Total\:Outcomes=6}$

$\longmapsto\tt{Favourable\:Outcomes=2(3,6)}$

$\longmapsto\tt\bold{Probability=\frac{No.\:of\:fav.\:Outcomes}{Total\:no.\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{2}{6}}$

$\longmapsto\tt\bold{\dfrac{1}{3}}$

So , The probability of getting a number which is divisible by 3 is 1/3..

Probability :

It is defined as chances of happening or occuring of an event.

• Probabilty of an event lies between 0 and 1.
• Probabilty can never be negative.
