Question

two coins are tossed simultaneously. what is the probablity of getting at least one head​

Answer 1

Answer:

When two different coins are tossed randomly, the sample space is given by

S = {HH, HT, TH, TT}

Therefore, n(S) = 4.

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

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

P= 3/4
