Question

two coins are tossed simulatneously list out outcomes also find the probability of getting
a)atleast one on head
b)more tail than head
c)a doublet
d)two tails

Answer 1

( A ) atleast one on head

Answer 2

Here, H - head & T - tail

S = {HH ,TT, HT, TH}

n (S)=4

a = {HH ,HT , TH}.

n(a)=3
$p \: (a) = \frac{3}{4}$
b = {TT}

n(b)=1
$p \: (b) \frac{1}{3}$
c ={HH,TT}

n(c)=2

$p \: (c) = \frac{2}{4} \\ \\ \: \: \: \: \: \: \: \: \: \: = \frac{1}{2}$
d={TT}

n(d)=1
$p(d) = \frac{1}{4}$
