- 1/2 * 2/6 = 1/6

- probability for coin show tail = 1/2.
probability for cube is = 2/6 =>1/3(composite no on cube is 4 and 6) - 10 years agoHelpfull: Yes(9) No(2)
- The probability of getting tail when coin tossed is 1/2 and probability of getting composite number when cube is rolled is 2/6 since only 4 and 6 are composite now the question asked is combination of both so 1/2*2/6 = 1/6 is the answer

- coin probability 1/2 ;for cube 3/6 (1,4,6 are composite) ans is=1/4
- 10 years agoHelpfull: Yes(4) No(11)
- Probability of getting tail = 1/2
Probability of getting composite number on a cube = 2/6 ( 4,6 are composite numbers)
so, probability of showing tail AND composite = 1/2 * 2/6 = 1/6 - 10 years agoHelpfull: Yes(2) No(0)
- probability for coin show tail = 1/2.
probability for cube is = 1/3 in that following as [H,H],[H,T],[T,H],[T,T] according this that tails shows have cube probability is =1/3. - 10 years agoHelpfull: Yes(1) No(5)
- (1/2)+(1/3)=5/6 is right ans.

- Number cubes contains 6 faces (1,2,3,4,5,6) in which composite numbers are(1,4,6).Composite number means the number which are not prime.
And for a coin there r two faces (H,T). So, if both of them will roll together then possibility of coming tail is 1 and for cube possibility of coming composite number is 3(1,4,6). So probability is
= 1*3/6*2
= 1/4 - 10 years agoHelpfull: Yes(1) No(7)
- 2/6*1/2 + 1/2 * 2/6

- probability for coin show tails is = 1/2.
probability for cube is = 1/6.

- (1/2)*(3/6)=1/4
3/6=prob.for composite number on the cube - 10 years agoHelpfull: Yes(0) No(6)
- total no of possible cases when both a cube rolled and a coin tossed = 12
no of possibe cases when the cube gives a composite no and the coin a tail = 2
the probability = 2/12= 1/6 - 10 years agoHelpfull: Yes(0) No(4)
- 1/6 is the answer
- 9 years agoHelpfull: Yes(0) No(0)
- 1/2*4/6 because 1,2,3,5 are composite numbers
- 9 years agoHelpfull: Yes(0) No(1)
- composite numbers starts from 4,6,8,9,............,so prob of cube is 2 /6 and prob of getting tail is 1/2 so total prob is 1/2*2/6=1/6.
