Question

a box contains cards numbered from 6 to 50. a card is drawn at random from the box. calculate the probability that drawn card is a perfect square.​

Answer 1

Answer:

favorable outcome = 2

E = perfect square no

p(E) = formula

= 2/45

Answer 2

favorable outcome is

S=(6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24, 25 26 27 28 29 28 13 31 32 33 34 35 36 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50)

n(S)=45

event A is getting perfect square

A=( 9 16 25 36 49 )

n(A)=5

P(A)=5/45

=1/9
