Step-by-step explanation:
i.p(getting 2 heads)=no.of trials which get 2 heads /total no. of trials
=138/600
=23/100 ans.
similarly,
ii.p(getting 1 head)=192/600
=8/25 ans.
iii.p(getting a head)=(138+192)/600
=330/600
=11/20 ans.
iv. it has same answer as that of qñ no.iii.
v.it has same answer as that of qñ no. ii.
