Question

please do this sum tomorrow is my exam

Answer 1

Total number of coins tossed = 2

The sample space n(S) = {HH,HT,TH,TT} = 4.

Let A be the event of getting atleast one head.

n(A) = {HH,TH,HT} = 3.

Required probability P(A) = n(A)/n(S) = 3/4.

It is a compound event because it has more than one possible outcome.

Hope it helps!

Answer 2

Sample space =4
P(A)=3/4
