Question

2) Iftwo coins are tossed, find the probability of the event that getting at least one head.
​

Answer 1

Answer:

probability of getting at least one head =  3/4

probability of gettin no head =1/4

Step-by-step explanation:

According to given condition we are tossing two coins.

If we toss two coins together the possibility of outcomes will be

(Head, head), (head, tail), (tail, head) , (tail, tail)

So, there can be 4 outcomes of tossing two coins together.

(1) probability of getting at least one head =

Answer 2

total no of outcome =2(head and tail)

so probability getting a tail =number of tail appeared^total number of possible outcome

=1^2
