Question

2. A coin is tossed and a die is rolled simultaneously.

0) Condition for eventA: To get a tail and an even number.

b) Condition for event B : To get a head or a tall and an odd number.​

Answer 1

A coin is tossed we get

➠ ( H , T )

A die is rolled we get

➠ ( 1 , 2 , 3 , 4 , 5 , 6 )

Answer for condition for event A

$➠P ( tail) = \frac{</p><p>favourable \: outcome }{</p><p> total \: outcome}$

$➠\: P ( tail) \: = \frac{1}{2}$

$➠P( even \: number ) = \frac{favourable outcome }{ total outcome}$

$➠P( even number ) = \frac{3}{6} </p><p>$

$➠P( even number ) = \frac{1}{2} </p><p>$

Answer for condition event B

$➠P ( head \: or \: tail ) = \frac{favourable \: outcome }{ total \: outcome}$

$➠P ( head \: or \: tail) = \frac{2}{2}$

$➠P ( head \: or \: tail) = 1$

$➠P( odd\: number ) = \frac{favourable outcome }{ total outcome}$

$➠P( odd \: number ) = \frac{3}{6}$

$➠P( odd \: number ) = \frac{1}{2}$
