Question

in a simultaneous toss of two coins what is the probability of getting no tail​

Answer 1

two coins are tossed

prob of getting tail=1/2

prob of getting head=1/2

sample space={(h,h);(h,t);(t,h);(t,t)}=4

so getting no tail is only one possibility that u get 2 heads

so prob of getting no tail=1/4

hope this helps
