Answer 2

$\huge\mathcal\red{AnSwEr:}$

$\huge\mathfrak\green{(i):}$

P (of getting 2 heads) =

$\frac{72}{200}$

$\bold{ \frac{9}{25} }$

$\huge\mathfrak\blue{(ii):}$

P(of getting at least 1 tail) =

77+72+78/200 =

$\bold{ \frac{177}{200} }$

$\huge\mathfrak\orange{(iii):}$

72+23/200

${ \frac{95}{200} }$

$= \bold{ \frac{19}{40} }$
