Question

A bag contains 12 beads julia takes a bead from the bad at random

Answer 1

Answer:

answer is 1 upon 12..........

Answer 2

Concept:

We first need to recall the concept of probability to solve this question.

Probability refers to the chance that a given event will occur.

Given:

A bag containing a total of 12 beads .

To find:

The probability of taking a bead from the bag at random.

Solution:

If E be a event

Then the probability of event E is given by:

P(E) = $\frac{Number\; of\;outcomes\;favourable\; to\; E }{Number\;of\;all\;possible\;outcomes\; of \;the \; experiment}$

    E = Choosing a bead at random form the bag

Number of favourable outcomes = 1           (i.e. number of beads choosed)

Number of all possible outcomes = 12         (i.e. total number of beads)

Probability P(E) = $\frac{1}{12}$

Hence,Probability of choosing a bead from bag at random is  $\frac{1}{12}$ .
