$18-25$	$320, 125, 75, 45, 30$
$25-40$	$400, 45, 50, 15, 10$
$40-55$	$150, 85, 13, 8, 10$
Above $55$	$150, 25, 17, 20, 7$

$1$	$62$
$2$	$72$
$3$	$78$
$4$	$91$
$5$	$85$

If one of the tests is chosen at random,find the probability that the student scored $(1)$ more than $90$ marks and $(2)$ between $70$ and $80$ marks in that test.
