Question

can anyone answer it pls

Answer 1

Hello there,

I hope my answer is correct.

a) 135/230=27/46

b) 130/230=13/23

c) 10/230=1/23

Make the problem like this,

More than 1750 : 10

More than 1775 : 45

.......

Hope you got the correct answer.

Please mark it as the brainliest of this is correct.

Answer 2

first of all we have to find out the n(s) of the given observation
so, n(s) = 10+45+75+60+40
= 230
now,
let A be the event of getting rs 1800 or more but less than rs.1825
therefore, n(A) = 75

therefore p(A) = n(A)/n(s)
= 75/230
= 17/46

now,
let b be the event of getting below rs 1825
so, n(b) = 10+45+75
= 130

therefore, p(b)= n(b)/n(s)
= 130/230
=13/23
now,
let c be the event of getting at least rs1775
so, n(c) = 10

therefore, p(c) = n(c)/n(s)
=10/230
=1/230
