Answer:
head = 60 tail = 90 LCM = 3
Step-by-step explanation:
now we divide 3 with 60 and 90
which = tail = 3/60 = 20
which = heads = 3/90 = 30
probability = 20+30 = 50
probability of heads = 20/50 in which 0 and 0 of 20 and 50 cut = 2/5
probability of tails = 30/50 in which again 0 of 30 and 0 of 50 cut = 3/5
∴probability of heads = 2/5
∴probability of tails = 3/5
