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

me! what did you put for this question?
