$P_1=$ Probability of clearing exam in 1 st attempt=0.5

$P_2=$ Probability of clearing exam in 2 nd attempt=0.7

$P_3=$ Probability of clearing exam in 3 rd attempt=0.8

Probability that she passes the exam $=P(1 st\ attempt)+P(1\ fail)\cdot P(2\ pass)+P(1\ fail)\cdot P(2\ fail)\cdot P(3 rd pass)$

$P=0.5+0.5\times 0.7+0.5\times 0.3\times 0.8=0.97$

(b)P(Pass qualification on 2nd try|passes qualification)

P(Pass qualification on 2nd try|passes qualification) $=\frac{P(fail\ on\ 1 )\cdot P(pass\ in\ 2nd)}{P(passes)}$
