Question

These marbles are placed in a bag and two

Answer 1

Heyy there!

Look below ↴

$\boxed{Probability = \frac{Favourable \: outcome}{Total \: outcome} }$

• Favourable outcome = 2
• Total outcome = 10

$\frac{2}{10}$

$\cancel\frac{2}{10} = \frac{1}{5}$

So, Now there is also a second draw. And to get the probability of that second draw, Multiply the fraction we reduced just now with the original fraction I.e. ↴

$\large\frac{1}{5} \times \frac{2}{10}$

$\sf = \frac{1}{25} \: or \: 25$

• Therefore, The probability of drawing a yellow marble is 1:25
