Answer 1

Answer:

i) 58/90 ii) 12/90

Step-by-step explanation:

i) No of possibilities is

We want two digit no then we have to minus starting 9 digits and also we want no less than 67 so we'll minus 23 no also so

our total no of possible events will be = 90-9-23

                                                               = 58

P(E) = 58/90

ii) As we know 12×7=84 and 13×7=91

∴ There are 12 no between 1 to 90 divisible by 7

P(E)= 12/90
