Question

please answer this question in the photo q7

Answer 1

There are 102 marked cards in a box.

So the possible outer come = 102

i) since perfect square are :-

1,4,9,16,25,36,49,64, 81,100

So, the favorable outcomes = 10

So P( number of perfect square) =

Number of favorable outcomes / Number of possible outcomes

= 10/102

= 5/51

ii)since prime number less than 24 are :-

2,3,5,7,11,13,19,23

So,favorable outcomes =8

So,P(prime number less than 24 )=

Number of favorable outcomes /Number of possible outcomes

=8/102

4/51
