Question

A bag contains cards numbered from 1 to 10 one card is drawn at random from the bag. Find the probability of getting a cube

Answer 1

Answer:

Total no. of cards = 10

P( getting a cube ) = N(E)/N(S) [ since 8 is the only cube between 1 to 10 ]

                               = 1/10

Answer 2

Total number of cards n(S)

=10

The probability total number of cubes n(A) ={1, 8}=2

• probability of getting a cube p(A) =n(A)

n(s)

=>2÷10

=>1/5
