Question

One day children invite some friends in their house and they want to play some fun game. So, they

consider block in the shape of a cube with one letter/number written on each face as shown below

a) Find the probability of getting an alphabet.

i) 1 ii) 1/3 iii)1/2 iv)2/3

b) Find the probability of getting a prime number

i) 2/3 ii)1/3 iii)1 iv) none of these

c) Find the probability of getting a consonant i) 1/3 ii) 1/6 iii)5/6 iv)2/3

d) When we have no reason to believe that one event is more likely to occur than the other, then it

is said to be

i) Simple event ii) compound event iii) equally likely outcomes iv) none of

these

e) If the probability of any event is one, then it is how much percentage

i) 1% ii)50% iii)100% iv)0%​

Answer 1

Answer:

a ) Option ( ii ) 1 / 3

P( Getting an alphabet ) = 2 / 6 = 1 / 3

b ) Option ( i ) 2 / 3

P ( Getting a prime number ) = 4 / 6 = 2 / 3

c ) Option ( ii ) 1 / 6

P ( Getting a consonant ) = 1 / 6

d ) Option ( iii ) Equally Likely Outcomes

e ) Option ( iii ) 100%

Probability = 1

Percentage = ( 1 / 1 ) * 100 = 100%
