Answer 1

Answer:

1 . P ( first class I.e. at least 60 % marks ) = 147 / 355

2. P ( Marks between 70 % and 80 % ) = 150 / 355 = 30 / 71

3. P ( 75% or above ) = 161 / 355

4. P ( less than 65 % marks ) = 120 / 355 = 24 / 71

Step-by-step explanation:

As total sum of all the information is 355 so total outcomes are 355

and the thing asked in question can be put into favourable outcomes ....

As

P( ) = Favourable outcomes / Total outcomes
