Question

If a bead thrown upward falls down on a chess board , what is the probability of it
falling in the white square?

Answer 1

Given:

A bead thrown upward falls down on a chess board.

To find:

What is the probability of it falling in the white square.

Solution:

Total number of squares in a chess board : 8×8=64 squares

Number of white squares (favourable outcomes) 64 ÷ 2 = 32

Probability = $\frac{Number of favourable outcomes}{Total number of outcomes}$

Probability of a bead falling in the white square = $\frac{Number of white squares}{Total number of squares}$

                                                                                = $\frac{32}{64}$

                                                                                 = $\frac{1}{2}$

So the probability of it falling in the white square is $\frac{1}{2}$
