Question 1.

In a village fair, there are 3 popular snacks available: Samosa, Pakora, and Bhaji. For drinks, villagers can choose either Chai or Lassi.

i. List the sample space of all possible snack and drink combinations a person could choose at the fair. Class 9

ii. List the event 'Selecting Samosa as a snack.'

Solution:

i. Snacks : {Samosa, Pakora, Bhaji}

Drinks : {Chai, Lassi}

∴ Sample space S = {(Samosa, Chai), (Samosa, Lassi), (Pakora, Chai), (Pakora, Lassi), (Bhaji, Chai), (Bhaji, Lassi)}

ii. Event: Selecting Samosa as a snack E = {(Samosa, Chai), (Samosa, Lassi)}

Question 2.

Can you calculate the probability of getting one head and one tail? Class 9

Answer:

Sample space: S = {HH, HT, TH, TT}

Event: Getting one head and one tail = {HT, TH}

Probability (one head and one tail)

= $\frac{2}{4}$ = 0.5
