Answer:
21/100
Step-by-step explanation:
two coins toss means sample space =( HH, HT, TH ,TT)
all time heads occur atleast one time. if tail is occur on both coins means 0 heads...
no. of two tails occur = 42 times
probability oh heads = no. of two tails occur/ total no. of coins tossed
p( 0 heads) = 42/200
= 21/100
