Anumber is selected at random from the set (1,2,3,4,5,6,7,8,9,10). let 'a' be the event that a number greater than 6 is selected and 'b' be the event that a 'square' is selected.
a) list the sample space.
b) list the events a and b
c) list a 'u' b
d) find pr (a)
e) find pr (a 'u' b)
me pleae.

Step-by-step explanation:

a) sample space = 10

I.e the total number of possible outcomes

b) A = {7,8,9,10 }

B = {4,9

c) A U B = {4,7,8,9,10}

d) pr (A) = no of events in A÷ total sample space

pr (A) = 4/10

=2/10

e) pr( A U B) = 5/ 10

= ½

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
