Question

7. There are 5 marbles in a bag with numbers 1 to 5 marked on each of them. What is the
probability of drawing a marble with number
(a) 5
(6) 4
(c) 2​

Answer 1

Given

• There are 5 marbles in a bag.
• Numbers from 1 to 5 are marked on each marble.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

(a) 5

Number of 5s in the bag = 1

⠀⠀

$\small\rm Probability = \dfrac{Favorable~outcomes}{Total~number~of ~outcomes}$

⠀⠀

$~~\leadsto~~\rm Probability = \dfrac{1}{5}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

(b) 4

Number of 4s in the bag = 1

⠀⠀

$\small\rm Probability = \dfrac{Favorable~outcomes}{Total~number~of ~outcomes}$

⠀⠀

$~~\leadsto~~\rm Probability = \dfrac{1}{5}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

(c) 2

Number of 2s in the bag = 1

⠀⠀

$\small\rm Probability = \dfrac{Favorable~outcomes}{Total~number~of ~outcomes}$

⠀⠀

$~~\leadsto~~\rm Probability = \dfrac{1}{5}$
