Question

One number is chosen for the number 1 to 100. find the probability that the number chosen is :
(i)a cube (ii)not a square
(iii)a multiple of11​

Answer 1

Answer:

(1)Number of favourable outcomes=4(1,8,27,64)

Total no. of outcomes=100

p(....)=4/100

1/25

Answer 2

Answer:(i) 4/100

(ii)9/10

(iii)9/100

Step-by-step explanation:(i) Cubes from 1-100

= 1,8,27,64

∴4/100

(ii) Squares from 1-100

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

there are total 10 squares

∴ $\frac{100-10}{100}$

=90/100 = 9/10

(iii)total no of multiples of 11 from 1-100= 9

∴ 9/100
