Question

a bag contains 5 blue sticks 4 red sticks and 3 orange sticks and you ask a friend to pick one without looking what is the prabability that the stick will be blue ?

Answer 1

Answer:

The answer is 5/12

Step-by-step explanation:

Here the total no of balls are 12 and no of blue balls are 5.

So probability= favourable outcomes/Total no of outcomes.

Therefore 5/12.

Hope this helps you.

Answer 2

The answer is 5/12

Given,

A bag contains blue sticks $= 5$

A bag contains red sticks $= 4$

A bag contains orange sticks $= 3$

To find :

Probability of picking up a blue stick ,

Solution:

The total no of sticks $= 5+ 4+ 3 = 12$

No. of blue sticks $= 5$

So probability= $\frac{no. of blue sticks}{Total no. of sticks } =\frac{5}{12}$

Definition of probability

• the chance that a given event will occur

• the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes

• a branch of mathematics concerned with the study of probabilities

• something (such as an event or circumstance) that is probable

• the quality or state of being probable

• a logical relation between statements such that evidence confirming one confirms the other to some degree
