Question

a die and two coins are tossed. the probability that both the coins show heads and die shows 1 or 2, is

Answer 1

Answer:

1 / 12

Step-by-step explanation:

Recall:

 P(a AND b) = P(a) × P(b),  for independent events a and b.

So...

P( 1st coin shows H  AND  2nd coin shows H  AND  die shows 1 or 2 )

= P(1st coin shows H ) × P(2nd coin shows H) × P(die shows 1 or 2)

= 1/2  ×  1/2  ×  2/6

= 1/2  ×  1/2  ×  1/3

= 1 / 12
