Question

In a bag, there are three different colored balls, that is, yellow, blue and red. A student is asked to pick a ball without looking into the bag. This was repeated $10$ times and each time the result was recorded.

Blue	Yellow	Red
$4$	$5$	$1$

Find the probability of picking a blue ball.

Answer 1

Let's find the probability of drawing a blue ball:

Probability of an outcome, $P\left(O\right)$ $=\frac{thenumberoftimesthefavourableoutcomeoccurs}{thetotalnumberoftimestheexperimentisdone}$

The number of times the outcome is a blue ball $=4$

The total number of times the experiment is done $=10$

Then, $P\left(B\right)$ $=\frac{4}{10}$

$=\frac{4÷2}{10÷2}$ ( reducing the fraction to its lowest form )

$=\frac{2}{5}$

Hence, the probability of getting blue as an outcome is $\frac{2}{5}$.
