Question

two coins are tossed simultaneously. find the probability of getting at least one tail​

Answer 1

Answer:

The probability could be 1/2

Answer 2

Answer:

3/4

Step-by-step explanation:

The possible outcomes when two coins are tossed together are {HH,TT,HT,TH}. Therefore, the number of possible outcomes when two coins are tossed is 4.

Now, the possible outcomes of getting at least one tail are {TT,HT,TH}, which means the number of favourable outcome is 3.

 

Therefore, probability P of getting at least one tail is:  

P= 3/4

 

Hence, the probability of getting at least one tail is  3/4.
