Question

2. A coin is tossed twice. Write down all the possible outcomes and find the probability of getting one head.​

Answer 1

Answer:

2 (50%)

Step-by-step explanation:

Total outcome = 2 (a coin has only 2 sides)

Favourable outcome (chance to get head) = 1 (only one side is heads)

Probability = Total outcome / Favourable outcome

= 2/1

= 2

So, we can conclude that the chance of getting an heads is 50%

Answer 2

Given,

A coin is tossed twice.

We know that, a coin has two faces, one heads and other tails.

So, the number of possible outcomes for each toss $=2$(one heads and one tails).

Then, the number of possible outcomes, if coin is tossed twice $=2\times2=4$.

Here, getting heads on the toss is the favorable outcome.

So, the number of favorable outcome for each toss $=1$ (only one heads)

Then, the number of favorable outcomes, if coin is tossed twice $=1\times2=2$.

We know that. probability $= \frac {number of favorable outcomes} {number of possible outcomes}$

So, probability of getting one head $= \frac {2} {4}$

$= \frac {1} {2}$.

Hence, probability of getting one head is $\frac {1} {2}$.
