If a number cube is rolled once and coin is tossed once. What is the probability that the coin will show tails and composite number on the cube?
a. 1/8
b. 1/16
c. 1/2
d. 1/4

• composite number on dice are 4 and 6.
  so the probability that the coin will show tails and composite number on the cube = (1/2) *(2/6) = 1/6

• composite numbers are 4,6
  so probability of getting composite numbers on cube is 2/6 = 1/3
  and probability of getting tail is 1/2
  so the answer is 1/2*1/3 = 1/6
  options are incorrect.

• 1 is neither prime nor composite...

• options are incorrect
  correct ans is 1/6

• composite number on dice is 4 and 6
  nd total probabaility of 1 dice rolled and one coin tossed is 8 so the probability that coil will show tails and composite number on cube is 2/8 i.e.,,, 1/4

• Compsit nos 1,4,6
  prob =3/6=1/2
  tails prob=1/2
  req probabilty=1/2*1/2=1/4
  d is correct

• as 1 is neither PRIME nor COMPOSITE...........composite numbers on dice are
  4 and 6 onlyy..........
  so the probability that the coin will show tails and composite number on the cube = (1/2) *(2/6) = 1/6

• composite nos on dice are 4 and 6 only
  prob(tail) = 1/2
  prob(c.no) = 2/6
  total probability = 1/2* 2/6 = 1/6

• The composite no.s on the die are 1,4,6.
  (note that 1 is not a prime no..
  so probability of getting composite no. is 3/6 and prob of obtaining a tail is 1/2.
  Required probability=3/12
  =1/4

• Compsit nos 1,4,6
  prob =3/6=1/2
  tails prob=1/2
  req probabilty=1/2*1/2=1/4
  d is correct.
