if 30 marks =30/50=3/5

if 35 marks =35/50=7/10

if there are 2 answers to this question then it is

probability for coming 30=3/5

probability for coming 35=7/10

but if it is a single answer then i may take a guess .

The Brainliest Answer!

Possible outcomes=(0,1,2,3,4.........50)

Number of possible outcomes=51

Probability of scoring 30=1/51 (since there is only 1 chance of 30 coming)

Probability of scoring 35=1/51 (same reason as above)

Total probability=1/51+1/51=

Ans:The probability that he scores 30 marks or 35 marks is 2/51.
